middle-end/101530 - fix shufflevector lowering
This makes __builtin_shufflevector lowering force the result
of the BIT_FIELD_REF lowpart operation to a temporary as to
fulfil the IL verifier constraint that BIT_FIELD_REFs should
be always in outermost handled component position. Trying to
enforce this during gimplification isn't as straight-forward
as here where we know we're dealing with an rvalue.

* c-common.c (c_build_shufflevector): Wrap the BIT_FIELD_REF
in a TARGET_EXPR to force a temporary.
gcc/testsuite/
* c-c++-common/builtin-shufflevector-3.c: New testcase.
