Summary:
There's no behavior change - just moving DependencyScanningTool to its own file
since this tool can be reused across both clang-scan-deps binary and an interface
exposed as part of libClang APIs.

Looks like on windows googlemock regexes treat newlines differently
from on darwin.    This patch fixes the regex in this test so it
will work on both.

Summary:
With this patch, only the no-argument form of `Reset()` remains in
PythonDataObjects.   It also deletes PythonExceptionState in favor of
PythonException, because the only call-site of PythonExceptionState was
also using Reset, so I cleaned up both while I was there.

Android links the unwinder library to every DSO. The problem is,
unwinder has global state, and hwasan implementation of personality

This doesn't use the default value, so doesn't benefit from the hack
to help optimize it.

Only handle simple inter-block redefs of m0 to the same value. This
avoids interference from redefs of m0 in SILoadStoreOptimzer. I was
initially teaching that pass to ignore redefs of m0, but having them
not exist beforehand is much simpler.

This is in preparation for deleting the current special m0 handling in
SIFixSGPRCopies to allow the register coalescer to handle the
difficult cases.

r375293 removed the SGPR spilling with scalar stores path, so this is

If a PHI defines AGPR legalize its operands to AGPR.
At the moment we can get an AGPR PHI with VGPR operands.
I am not aware of any problems as it seems to be handled
gracefully in RA, but this is not right anyway.

It also slightly decreases VGPR pressure in some cases
because we do not have to a copy via VGPR.
