llvm-6502/test/MC/Mips/mips-bad-branches.s
Matheus Almeida b90ed644fc [mips] Add checks for alignment and maximum displacements for most of the 
branch instructions for mips and micromips instruction sets thus avoiding
the situation of generating branches to undesired locations if offsets
cannot be encoded.

This patch also checks if a fixup cannot be applied and returns a fatal error
if that's the case.
