This patch does two things. First, it canonicalizes 'X >= C' -> 'X > C-1'
(likewise for <= >=u >=u).
Second, it implements a special case hack to turn 'X gtu SINTMAX' -> 'X lt 0'
On powerpc, for example, this changes this:
lis r2, 32767
ori r2, r2, 65535
cmplw cr0, r3, r2
bgt .LBB_test_2
into:
cmpwi cr0, r3, 0
blt .LBB_test_2
