diff_plist"
Following r363007, which reverted r362998, r362996, and r362994,
reapply with adjustments for the CRLF differences encountered with
Windows. Namely, the `-b` option of `diff` is employed, and the `grep`
patterns have `$` replaced with `[[:space:]]*$`.

diff_plist"
Reverts r362998, r362996, and r362994 because the tests do not pass on
Windows due to CRLF changes. Adding back `-w` to diff is not enough, the
new grep substitution doesn't work on Windows, and fixing it is
non-trivial.

Summary:
The `%diff_plist` lit substitution invokes `diff` with a non-portable
`-I` option. The intended effect can be achieved by normalizing the
inputs to `diff` beforehand. Such normalization can be done with
`grep -Ev`, which is also used by other tests.
This patch applies the change (adjusted for review comments) described
in http://lists.llvm.org/pipermail/cfe-dev/2019-April/061904.html
mechanically to the cases where the output file is piped to
`%diff_plist` via `cat`.
The changes were applied via a script, except that
`clang/test/Analysis/NewDelete-path-notes.cpp` and
`clang/test/Analysis/plist-macros-with-expansion.cpp` were each adjusted
for the line-continuation on the relevant `RUN` step.

The current argument order has "expected" and "actual" the wrong way around,
so that the diff shows the change from expected to actual, not from actual to expected.
Namely, if the expected diagnostics contains the string "foo", but the analyzer emits "bar",
we really want to see:
```
- foo
+ bar
```
not
```
- bar
+ foo
```
since adapting to most changes would require applying that diff to the expected output.

files, use diff instead of a FileCheck
Some of the analyzer tests check the exact plist output, in order to
verify that the diagnostics produced is correct.
Current testing setup has many issues:
plist output clobbers tests, making them harder to read
it is impossible to debug test failures given error messages from FileCheck.
The only recourse is manually creating the files and using the diff
again, it is impossible to update the tests given the error message:
the only process is a tedious manual one,
going from a separate plist file to CHECK directives.
This patch offers a much better approach of using "diff" directly in place of FileCheck,
and moving tests to separate files.
Generated using the following script:
```
import os
import glob
import re
import subprocess
diagnostics_key = "// CHECK: <key>diagnostics</key>"
def process_file(f, data):
idx = data.index(diagnostics_key)
plist_out_f = 'ExpectedOutputs/plists/%s.plist' % f
plist_out_folder = os.path.join('ExpectedOutputs/plists/', os.path.dirname(f))
plist_data = data[idx:]
plist_data = plist_data.replace('// CHECK: ', '')
plist_data = plist_data.replace('// CHECK-NEXT: ', '')
plist_data += "</dict>\n</plist>\n"
data = data[:idx]
ptn = re.compile("FileCheck --?input-file(=| )(%t|%t\.plist) %s")
if not ptn.findall(data):
print "none found =/ skipping..."
return
data = ptn.sub(lambda m: "tail -n +11 %s | diff -u -w - %%S/../%s" % (m.group(2), plist_out_f), data)
with open(f, 'w') as out_f:
out_f.write(data)
subprocess.check_call(["mkdir", "-p", plist_out_folder])
with open(plist_out_f, 'w') as out_f:
out_f.write(plist_data)
def main():
files = glob.glob("**/*.*")
for f in files:
with open(f) as f_handler:
data = f_handler.read()
if diagnostics_key in data:
print "Converting %s" %f
process_file(f, data)
if __name__ == "__main__":

Rename AlternateExtensive to Extensive.
In 2013, five years ago, we have switched to AlternateExtensive
diagnostics by default, and Extensive was available under unused,
undocumented flag.
This change remove the flag, renames the Alternate
diagnostic to Extensive (as it's no longer Alternate), and ports the
test.

This patch adds hashes to the plist and html output to be able to identfy bugs
for suppressing false positives or diff results against a baseline. This hash
aims to be resilient for code evolution and is usable to identify bugs in two
different snapshots of the same software. One missing piece however is a
permanent unique identifier of the checker that produces the warning. Once that
issue is resolved, the hashes generated are going to change. Until that point
this feature is marked experimental, but it is suitable for early adoption.

...but don't yet migrate over the existing plist tests. Some of these
would be trivial to migrate; others could use a bit of inspection first.
In any case, though, the new edge algorithm seems to have proven itself,
and we'd like more coverage (and more usage) of it going forwards.

Before:
1. Calling 'foo'
2. Doing something interesting
3. Returning from 'foo'
4. Some kind of error here
After:
1. Calling 'foo'
2. Doing something interesting
3. Returning from 'foo'
4. Some kind of error here
The location of the note is already in the caller, not the callee, so this
just brings the "depth" attribute in line with that.
This only affects plist diagnostic consumers (i.e. Xcode). It's necessary
for Xcode to associate the control flow arrows with the right stack frame.

In this code
int getZero() {
return 0;
}
void test() {
int problem = 1 / getZero(); // expected-warning {{Division by zero}}
}
we generate these arrows:
+-----------------+
| v
int problem = 1 / getZero();
^ |
+---+
where the top one represents the control flow up to the first call, and the
bottom one represents the flow to the division.* It turns out, however, that
we were generating the top arrow twice, as if attempting to "set up context"
after we had already returned from the call. This resulted in poor
highlighting in Xcode.
* Arguably the best location for the division is the '/', but that's a
different problem.

r176010 introduced the notion of "interesting" lvalue expressions, whose
nodes are guaranteed never to be reclaimed by the ExplodedGraph. This was
used in bugreporter::trackNullOrUndefValue to find the region that contains
the null or undef value being tracked.
However, the /rvalue/ nodes (i.e. the loads from these lvalues that produce
a null or undef value) /are/ still being reclaimed, and if we couldn't
find the node for the rvalue, we just give up. This patch changes that so
that we look for the node for either the rvalue or the lvalue -- preferring
the former, since it lets us fall back to value-only tracking in cases
where we can't get a region, but allowing the latter as well.
