Fix tree-optimization/103314 : Limit folding of (type) X op CST where type is a nop convert to gimple
There is some re-association code in fold_binary which conflicts with
this optimization due keeping around some "constants" which are not
INTEGER_CST (1 << -1) so we end up in an infinite loop because of that.
So we need to limit this case to GIMPLE level only.
OK? Bootstrapped and tested on x86_64-linux-gnu with no regressions.
PR tree-optimization/103314
gcc/ChangeLog:
* match.pd ((type) X op CST): Restrict the equal
TYPE_PRECISION case to GIMPLE only.
gcc/testsuite/ChangeLog:
* gcc.c-torture/compile/pr103314-1.c: New test.
