implementation
Summary:
A lot of our tests copied the setUp code from our TestSampleTest.py:
```
def setUp(self):
# Call super's setUp().
TestBase.setUp(self)
```
This code does nothing unless we actually do any setUp work in there, so let's remove all these method definitions.

that don't actually call 'print()'
Summary:
A lot of tests do this trick but the vast majority of them don't even call `print()`.
Most of this patch was generated by a script that just looks at all the files and deletes the line if there is no `print (` or `print(` anywhere else in the file.
I checked the remaining tests manually and deleted the import if we never call print (but instead do stuff like `expr print(...)` and similar false-positives).
I also corrected the additional empty lines after the import in the files that I manually edited.

I don't think this test case can be handled correctly on AAPCS64.
The ABI says that the caller passes the address of the return object
in x8. x8 is a caller-spilled (aka "volatile") register, and the
function is not required to preserve x8 or to copy the address back
into x8 on function exit like the SysV x86_64 ABI does with rax.
(from aapcs64: "there is no requirement for the callee to preserve the
value stored in x8")
From my quick reading of ABISysV_arm64, I worry that it may actually be
using the value in x8 at function exit, assuming it still has the
address of the return object -
if (is_return_value) {
// We are assuming we are decoding this immediately after returning from
// a function call and that the address of the structure is in x8
reg_info = reg_ctx->GetRegisterInfoByName("x8", 0);
This will work on trivial test programs / examples, but if the function
does another function call, or overwrites x8 as a scratch register, lldb
will provide incorrect values to the user.
ABIMacOSX_arm64 doesn't do this, but it also doesn't flag the value
as unavailable so we're providing incorrect values to the user all
the time. I expect my fix will be to make ABIMacOSX_arm64 flag
the return value as unretrievable, unless I've misread the ABI.

I have either opened new bug reports for these tests, or added links to
existing bugs.
This should help make the lldb-aarch64-ubuntu buildbot green (there will
still be some unexpected passes that someone should look into, but those
can be handled later).

Summary:
Instead of each test case knowing its depth relative to the test root,
we can just have dotest add the folder containing Makefile.rules to the
include path.
This was motivated by r370616, though I have been wanting to do this
ever since we moved to building tests out-of-tree.
The only manually modified files in this patch are lldbinline.py and
plugins/builder_base.py. The rest of the patch has been produced by this
shell command:
find . \( -name Makefile -o -name '*.mk' \) -exec sed --in-place -e '/LEVEL *:\?=/d' -e '1,2{/^$/d}' -e 's,\$(LEVEL)/,,' {} +

Summary:
The test suite has often unnecessary trailing whitespace, and sometimes
unnecessary trailing lines or a missing final new line. This patch just strips
trailing whitespace/lines and adds missing newlines at the end.

Windows
Summary:
1) When ReadRegister is called with a null register into on Windows, rather than crashing due to an access violation, simply return false. Not all registers and properties will be read or calculated correctly, but that is consistent with other platforms that also return false in that case
2) Update a couple of tests to reference pr37995 as their reason for failure since it is much more accurate. Support for floating point registers doesn't exist on Windows at all, rather than having issues.
