AArch64: make rules for CBZ/TBZ higher priority

Move the rules for CBZ/TBZ to be above the rules for
CBB<cond>/CBH<cond>/CB<cond>. We want them to have higher priority
because they can express larger displacements.

gcc/ChangeLog:

* config/aarch64/aarch64.md (aarch64_cbz<optab><mode>1): Move
above rules for CBB<cond>/CBH<cond>/CB<cond>.
(*aarch64_tbz<optab><mode>1): Likewise.

gcc/testsuite/ChangeLog:

* gcc.target/aarch64/cmpbr.c: Update tests.
