[AMDGPU][llvm-mc] Quickfix for r272748 to enable labels in branch instructions. Fixes issue mentioned at: https://github.com/RadeonOpenCompute/LLVM-AMDGPU-Assembler-Extra/issues/13. Lit tests added. Differential Revision: http://reviews.llvm.org/D22133 llvm-svn: 275054

// RUN: llvm-mc -arch=amdgcn -mcpu=fiji -show-encoding %s | FileCheck %s --check-prefix=VI
[AMDGPU] Fix s_branch with -1 offset Summary: In case s_branch instruction target is itself backend should emit offset -1 but instead it emit 0. ''' label: s_branch label // should emit [0xff,0xff,0x82,0xbf] ''' Tom, Matt: why are we adjusting fixup values in applyFixup() method instead of processFixup()? processFixup() is calling adjustFixupValue() but does nothing with its result.
