[Iain Sandoe <iains.gcc@gmail.com>]

tested on aarch64-apple-darwin21, pushed to trunk, thanks.

When we have '-O3 -g' we emit a bunch of LB{B,E} local labels which
were not currently being discarded, leading to some test fails.

Fixed by adding this case to the ignored labels.

gcc/testsuite/ChangeLog:

	* lib/scanasm.exp: Add 'LB*' to the local labels that are
	ignored for Darwin.
