[msan] Handle llvm.bitreverse by applying intrinsic to shadow (#125606)
llvm.bitreverse was incorrectly handled by the heuristic handler,
because it did not reverse the bits of the shadow.

This updates the instrumentation to use the handler from
https://github.com/llvm/llvm-project/pull/114490 and updates the test
from https://github.com/llvm/llvm-project/pull/125592
