This recursively strips all GEPs like the existing code. It also handles bitcasts and
other operations that do not change the pointer value.

Switch instructions were crashing the StructurizeCFG pass, and it's
probably easier anyway if we don't need to handle them in this pass.

infrastructure.

This was essentially work toward PGO based on a design that had several
flaws, partially dating from a time when LLVM had a different
architecture, and with an effort to modernize it abandoned without being
completed. Since then, it has bitrotted for several years further. The
result is nearly unusable, and isn't helping any of the modern PGO
efforts. Instead, it is getting in the way, adding confusion about PGO
in LLVM and distracting everyone with maintenance on essentially dead
code. Removing it paves the way for modern efforts around PGO.

Among other effects, this removes the last of the runtime libraries from
LLVM. Those are being developed in the separate 'compiler-rt' project
now, with somewhat different licensing specifically more approriate for
runtimes.

Summary:
As discussed in http://llvm-reviews.chandlerc.com/D1754,
this optimization isn't really valid for C, and fires too rarely anyway.

This partially addresses PR17435, but it doesn't actually implement the
pragma.  If we implement it, we should map levels 1-4 to something like
-Wall and level 0 to something like -w.

Patch by Alp Toker. Many thanks!

Original descriptions:
clang-format-diff incorrectly modifies unchanged lines due to an error
in diff parsing.

The unified diff format has a default line change count of 1, and 0 may
be specified to indicate that no lines have been added. This patch
updates the parser to accurately reflect the diff specification.

This also has the benefit of stabilising the operation so it will
produce the same output when run multiple times on the same changeset,
which was previously not the case.

No tests added because this script is not currently tested (though we
should look into that!)
