David Stenberg 95c6236239 [DebugInfo] Ignore bitcasts when lowering stack arg dbg.values ...

Summary:
Look past bitcasts when looking for parameter debug values that are
described by frame-index loads in `EmitFuncArgumentDbgValue()`.

In the attached test case we would be left with an undef `DBG_VALUE`
for the parameter without this patch.

A similar fix was done for parameters passed in registers in D13005.

This fixes PR40777.
