MATCH: Fix PR 109834, ICE with popcount combined with bswap
After r14-673-gc0dd80e4c4c3, there was a check in the match
patterns which was checking the type is unsigned but
instead of using the type, the patch used the expression.
This adds the needed TREE_TYPE so get the correct answer and don't ICE.
Committed as obvious after a bootstrap/test on x86_64-linux-gnu.
PR tree-optimization/109834
gcc/ChangeLog:
* match.pd (popcount(bswap(x))->popcount(x)): Fix up unsigned type checking.
(popcount(rotate(x,y))->popcount(x)): Likewise.
gcc/testsuite/ChangeLog:
* gcc.c-torture/compile/pr109834-1.c: New test.
* gcc.dg/tree-ssa/pr109834-1.c: New test.
