21c75f0b - [InstCombine][NFC] Change the order of checks in SliceUpIllegalIntegerPHI for faster compile time. (#183726)

[InstCombine][NFC] Change the order of checks in SliceUpIllegalIntegerPHI for faster compile time. (#183726) SliceUpIllegalIntegerPHI searches for PHIs that have illegal type and are only used by trunc or trunc(lshr) operations. It bails out if encounters invoke or EH pad instructions. It first checks whether it encounters invoke or EH pad, which is time consuming as it checks every instruction. Then it checks whether it is used by trunc or trunc(lshr). The former check is generally loose, while the latter one is stricter. Switch the order of the checks will speed up compilation. Signed-off-by: XinlongZHANG-Bob <zhangxinlong.bob@bytedance.com>
