[Patch] Fix AArch32 VSEL's condition inversion

[Weiming Zhao]

Hi,

 

In AArch32, in order to generate vsel, it may swap the operands of SELECT
and inverse the condition.

E.g.:

v = cond ? f0 : f1   =>  v = cond2 ? f1: f0, where cond2 is the inversion of
cond (i.e.  LE=>GT, EQ=>NE, GT =>LE .ect.)

Currently, it uses api getSetCCSwappedOperands, which only toggles L and G
bit, not E bit.

 

Please help to review the patch.

 

Thanks,

Weiming
