Check that getDebugInfo() is not null, as in the first revision, before
calling getDebugInfo()->addHeapAllocSiteMetadata().
Else would cause a crash with a new expression in a default arg.

Clang marks calls to operator new as heap allocation sites, but the
operator declared at global scope returns a void pointer. There is no
explicit cast in the code, so the compiler has to write down the
allocated type itself.
Also generalize a cast to use CallBase, so that we mark heap alloc sites
when exceptions are enabled.

With a change to use `CGM.getCodeGenOpts().getDebugInfo() != codegenoptions::NoDebugInfo`
instead of `getDebugInfo()`,
to fix `Profile-<arch> :: instrprof-gcov-multithread_fork.test`
See CodeGenModule::CodeGenModule, `EmitGcovArcs || EmitGcovNotes` can
set `clang::CodeGen::CodeGenModule::DebugInfo`.

[MS] Add metadata for __declspec(allocator)
Original summary:
Emit !heapallocsite in the metadata for calls to functions marked with
__declspec(allocator). Eventually this will be emitted as S_HEAPALLOCSITE debug
info in codeview.
