MATCH: Add some more value_replacement simplifications to match
This moves a few more value_replacements simplifications to match.
/* a == 1 ? b : a * b -> a * b */
/* a == 1 ? b : b / a -> b / a */
/* a == -1 ? b : a & b -> a & b */
Also adds a testcase to show can we catch these where value_replacement would not
(but other passes would).
Bootstrapped and tested on x86_64-linux-gnu with no regressions.
gcc/ChangeLog:
* match.pd (`a == 1 ? b : a OP b`): New pattern.
(`a == -1 ? b : a & b`): New pattern.
gcc/testsuite/ChangeLog:
* gcc.dg/tree-ssa/phi-opt-value-4.c: New test.
