Don't fold and's into test instructions if they have multiple uses.
This compiles test-nofold.ll into:
_test:
movl $15, %ecx
andl 4(%esp), %ecx
testl %ecx, %ecx
movl $42, %eax
cmove %ecx, %eax
ret
instead of:
_test:
movl 4(%esp), %eax
movl %eax, %ecx
andl $15, %ecx
testl $15, %eax
movl $42, %eax
cmove %ecx, %eax
