[LegalizeTypes] Use report_fatal_error instead of llvm_unreachable in the default...

These can be triggered by mistakenly using a 64-bit mode only intrinsics with a -mtriple=i686. Using report_fatal_error gives a better experience for this mistake in release builds instead of probably crashing.

We already do this for some of the vector type legalization handles.
