match: Delay folding of 1/x into `(x+1u)<2u?x:0` until late [PR113301]
Since currently ranger does not work with the complexity of COND_EXPR in
some cases so delaying the simplification of `1/x` for signed types
help code generation.
tree-ssa/divide-8.c is a new testcase where this can help.
Bootstrapped and tested on x86_64-linux-gnu with no regressions.
PR tree-optimization/113301
gcc/ChangeLog:
* match.pd (`1/x`): Delay signed case until late.
gcc/testsuite/ChangeLog:
* gcc.dg/tree-ssa/divide-8.c: New test.
