x86_64: Use TESTB instead of TESTL in CHECK_INVALID_LONGJMP
There is no need to use TESTL when checking the least-significant bit
with a TEST instruction. Use TESTB, which is three bytes shorter:
f6 44 24 f0 01 testb $0x1,-0x10(%rsp)
vs:
f7 44 24 f0 01 00 00 testl $0x1,-0x10(%rsp)
00
for the same effect.
No functional changes intended.
