Sylvain Audi 3f3438a596 [CodeGen][X86] Crash fixes for "patchable-function" pass ...

This patch fixes crashes related with how PatchableFunction selects the instruction to make patchable:
- Ensure PatchableFunction skips all instructions that don't generate actual machine instructions.
- Handle the case where the first MachineBasicBlock is empty
- Removed support for 16 bit x86 architectures.

Note: another issue remains related with PatchableFunction, in the lowering part.
