This test used to write a .s file until r266971 fixed that. But on most bots,
the .s file still exists. Add an rm statement to clean up the bots. In a few
days, this statement can go away again.

AArch64InstrInfo::optimizeCompareInstr has bug PR27158 which causes generation of incorrect code.
A compare instruction is substituted with another instruction which does not
produce the same flags as the original compare instruction.
This patch contains:
1. Fix of the bug.
2. A regression test in MIR.
3. A new test to check that SUBS is replaced by SUB.
