Changes

Remove HAVE_VCS_VERSION_INC, not needed

This preprocessor define was meant to be used to conditionally include VCSVersion.inc. However, the define was always set, and it was the content of the header that was conditionally generated. Therefore HAVE_VCS_VERSION_INC should be cleaned up.

[mlir][gpu] NFC: Change gpu.launch_func ops to custom format.

[CodeGen] Fix neutral value of vecreduce fadd in tests (NFC)

The neutral value is -0.0, not 0.0. This doesn't matter for "fast"
reductions due to nsz, but does matter for reassoc-only and seq
reductions.

Change tests to mostly use -0.0 where the neutral value was intended,
and add some additional test coverage in some places. Also update
LangRef to use the right value.

[SDAG] Fix neutral value for vecreduce_fadd

The neutral value for FADD is -0.0, not 0.0, so this is what we
need to pad vectors with.

[WebAssembly] Remove unused FileCheck test prefixes

This commit removes unused FileCheck prefixes from WebAssembly test files to
avoid causing test failures once FileCheck disallows unused prefixes by default.
See D90281 and the corresponding llvm-dev thread for context.
