Subject: Fix gcc.dg/tree-ssa/forwprop-42.c

The testcase requires hardware support for V2DImode vectors because
otherwise we do not rewrite inserts via BIT_FIELD_REF to
BIT_INSERT_EXPR.  There's no effective target for this so the
following makes the testcase x86 specific, requiring and enabling SSE2.

	* gcc.dg/tree-ssa/forwprop-42.c: Move ...
	* gcc.target/i386/pr111228.c: ... here.  Enable SSE2.
