  [WebAssembly] Fix incorrect DW_TAG_pointer_type size in test

It should be 64 bits not 32 for wasm64-unknown-unknown. I noticed this
because this test was failing in our CHERI fork of LLVM due to a larger
.debug_abbrev section size. It turns out this happens because we add
DW_AT_byte_size for non-default pointer sizes to allow debugging our
hybrid compilation mode where we can have two different kinds of pointers.

  [asan] Remove FreeBSD XFAIL from asan-sigbus.cpp test

This test passes for me on FreeBSD 12.2 and was probably fixed by

  Log Message:
  -----------
  [TableGen] Emit more helpful error messages on empty type set

I have seen this error quite frequently in our out-of-tree CHERI backends
and the lack of location information sometimes makes it quite difficult
to track down the actual source of the error.
This patch changes the llvm_unreachable() to a PrintFatalError() so that
tablegen prints a stack of source locations.
