Gerolf Hoflehner 2bddd7cf65 [AAarch64] Optimize CSINC-branch sequence 
Peephole optimization that generates a single conditional branch
for csinc-branch sequences like in the examples below. This is
possible when the csinc sets or clears a register based on a condition
code and the branch checks that register. Also the condition
code may not be modified between the csinc and the original branch.

Examples:

1. Convert csinc w9, wzr, wzr, <CC>;tbnz w9, #0, 0x44
   to b.<invCC>

2. Convert csinc w9, wzr, wzr, <CC>; tbz w9, #0, 0x44
   to b.<CC>
