aarch64: Generalise tbz_2.c

For many functions in tbz_2.c, it doesn't matter whether the code
tests a 32-bit or a 64-bit register.  g6-g8 have started testing
32-bit registers, but the others could in future too.

gcc/testsuite/
	* gcc.target/aarch64/tbz_2.c: Accept both 32-bit and 64-bit registers.
