philhofer c59b495963 cmd/compile: add support for arm64 bit-test instructions 
Add support for generating TBZ/TBNZ instructions.

The bit-test-and-branch pattern shows up in a number of
important places, including the runtime (gc bitmaps).

Before this change, there were 3 TB[N]?Z instructions in the Go tool,
all of which were in hand-written assembly. After this change, there
are 285. Also, the go1 benchmark binary gets about 4.5kB smaller.

Fixes #21361
