Aaron Ballman 3dd74b8edb Fix a relatively nasty bug with fs::getPathFromOpenFD() on Windows. The GetFinalPathNameByHandle API does not behave as documented; if given a buffer that has enough space for the path but not the null terminator, the call will return the number of characters required *without* the null terminator (despite being documented otherwise) and it will not set GetLastError(). The result was that this function would return a bogus path and no error. Instead, ensure there is sufficient space for a null terminator (we already strip it off manually for compatibility with older versions of Windows).

George Burgess IV d8cdc36f76 [MemorySSA] Clean up unit tests a tiny bit. NFC. 
We recently made MemorySSA own the walker it creates. As a part of this,
the MSSA test fixture was changed to have a `Walker*` instead of a
`unique_ptr<Walker>`. So, we no longer need to do `&*Walker` in order to
get a `Walker*`.

Matt Arsenault 2209625387 AMDGPU: Preserve undef flag on vcc when shrinking v_cndmask_b32

so this was adding an additional vcc use. The original one
was missing the undef flag the original condition had,
so the verifier would complain.

Etienne Bergeron 3ac879f9a6 Add missing decoding patterns toRoundUpToInstrBoundary 
Summary:
The RoundUpToInstrBoundary determines intructions boundary and it's used to determine how to patch (intercept) functions.

The current x64-bit implementation is incomplete. This patch is adding patterns observed when trying to sanitize a 64-bit executable on my computer.

Thw two current functions not intercepted are:

Initial commit message:
Patch implements basic support of versioned symbols.
There is no wildcards patterns matching except local: *;
There is no support for hierarchies.
There is no support for symbols overrides (@ vs @@ not handled).

This patch allows programs that using simple scripts to link and run.
