i386: Use TESTB instead of TESTL in ____longjmp_chk()
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 04 01 testb $0x1,0x4(%esp)
vs:
f7 44 24 04 01 00 00 testl $0x1,0x4(%esp)
00
for the same effect.
No functional changes intended.
