  [AMDGPU] Do not release VGPRs at -O0

This was an oversight when the GFX11 early release VGPRs optimization
was reimplemented in D153279.

Sending the DEALLOC_VGPRS message is a performance optimization so there
is no need to do it at -O0. In addition it makes some kinds of post
mortem debugging hard or impossible, since VGPR values are no longer
available to inspect at the s_endpgm instruction.

  [BPF] Don't crash on missing line info

When compiling Rust code we may end up with calls to functions provided
by other code units. Presently this code crashes on a null pointer
dereference - this patch avoids that crash and adds a test.

  [clang-tidy] fix None tmpdir when exporting fixes in run-clang-tidy

Differential https://reviews.llvm.org/D145477 removed the check for `(yaml and args.export_fixes)` in line 303 to skip looking for the `clang-apply-replacements` binary. However, the `tmpdir` variable was set in this true branch when exporting fixes and therefore is `None` when invoking run-clang-tidy with `run-clang-tidy -p . -export-fixes fixes.yaml`.
