i386: Fix up ix86_expand_int_sse_cmp [PR107585]

The following patch fixes ICE on the testcase.  I've used GEN_INT
incorrectly thinking the code punts on the problematic boundaries.
It does, but only for LE and GE, i.e. signed comparisons, for unsigned
the boundaries are 0 and unsigned maximum, so when say unsigned char
adds one to 127 or subtracts one from 128 we need to canonicalize it.
