ci: support workflow with sanitizers

[antonbaliasnikov]

What ❔

Add manual workflow to run compiler-tester with sanitizers enabled.

The workflow is working as follows:

1. Build LLVM with sanitizer specified with llvm-sanitizer parameter
2. Build FE compilers with sanitizer specified with rust-sanitizer parameter
3. Build compiler-tester itself with sanitizer specified with rust-sanitizer parameter

More info about Rust sanitizers is available here.
Possible values are: address, cfi, hwaddress, kcfi, leak, memory, or thread

Only memory and thread were tested and supported for now, although CI allows us to try other variations.

For more information about the supported sanitizers in LLVM, see this page.

Possible values for LLVM sanitizer are Address, Memory, MemoryWithOrigins, Undefined, Thread, DataFlow, and Address;Undefined.

Only Address and Thread were tested and supported for now, although CI allows us to try other variations.

Why ❔

Fixes CPR-1052

Testing

Thread and Address sanitizers tested:

• Address sanitizer workflow fails with memory leak reported here.

• Thread sanitizer workflow. (Timeout disabled tests execution after ~10 hours, no issues found. I disabled the timeout.)

  • With the Thread Sanitizer tests are running approx. at 100k tests per 2 hours rate.
  • It is suggested to reduce the number of tests or modes using input parameters to get some acceptable execution time.
