x86: Avoid stack realignment when copying data
To avoid stack realignment, use SCRATCH_SSE_REG to copy data from one
memory location to another.
gcc/
* config/i386/i386-expand.c (ix86_expand_vector_move): Call
ix86_gen_scratch_sse_rtx to get a scratch SSE register to copy
data from one memory location to another.
gcc/testsuite/
* gcc.target/i386/eh_return-1.c: New test.
