re PR target/34856 (ICE with some constant vectors)
PR target/34856
* simplifx-rtx.c (simplify_const_binary_operation) [VEC_CONCAT]:
Consider only CONST_INT, CONST_DOUBLE and CONST_FIXED as constant
vector elements.
testsuite/ChangeLog:
PR target/34856
* gcc.dg/pr34856.c: Use pointer mode for "pin".
