67; PR20354: when generating code for a vector fabs op,
68; make sure that we're only turning off the sign bit of each float value.
69; No constant pool loads or vector ops are needed for the fabs of a
70; bitcasted integer constant; we should just return an integer constant
71; that has the sign bits turned off.
72;
73; So instead of something like this:
74;    movabsq (constant pool load of mask for sign bits)
75;    vmovq   (move from integer register to vector/fp register)
76;    vandps  (mask off sign bits)
77;    vmovq   (move vector/fp register back to integer return register)
78;
79; We should generate:
80;    mov     (put constant value in return register)
