The only functional change here is that -coverage-notes-file is not
passed to -cc1 in some situations.
This code appears to be trying to put the gcno and gcda output next to
the final object file, but it's doing that in a really convoluted way
that needs to be re-examined. It looks for -c or -S in the original
command, and then looks at the -o argument if present in order to handle
the -fno-integrated-as case. However, this doesn't work if this is a
link command with multiple inputs. I looked into fixing this, but the
check-profile test suite has a lot of dependencies on this behavior, so
I left it all alone.

You can't use -fno-integrated-as for *-msvc triples because no usable
standalone assembler exists. Perhaps we could teach clang to emit a .s
and then reinvoke itself, but that's a bit silly.
Anyway, fix the test by using an Itanium ABI triple, which will become
mingw, which will assume gnu as is a usable assembler.

Changes the default Windows target triple returned by
GetHostTriple.cmake from the old environment names (which we wanted to
move away from) to newer, normalized ones. This also requires updating
all tests to use the new systems names in constraints.

-fprofile-dir=path allows the user to specify where .gcda files should be
emitted when the program is run. In particular, this is the first flag that
causes the .gcno and .o files to have different paths, LLVM is extended to
support this. -fprofile-dir= does not change the file name in the .gcno (and
thus where lcov looks for the source) but it does change the name in the .gcda
(and thus where the runtime library writes the .gcda file). It's different from
a GCOV_PREFIX because a user can observe that the GCOV_PREFIX_STRIP will strip
paths off of -fprofile-dir= but not off of a supplied GCOV_PREFIX.
To implement this we split -coverage-file into -coverage-data-file and
-coverage-notes-file to specify the two different names. The !llvm.gcov
metadata node grows from a 2-element form {string coverage-file, node dbg.cu}
to 3-elements, {string coverage-notes-file, string coverage-data-file, node
dbg.cu}. In the 3-element form, the file name is already "mangled" with
.gcno/.gcda suffixes, while the 2-element form left that to the middle end
pass.

I'm going to fix up FileCheck to better handle things like this soon,
but for now let's just unblock the Windows people.

Windows can't use -no-integrated-as, so split these tests out into a
separate file and XFAIL them for win32,win64.
