The Valgrind sources contain test programs, including expected outputs,
for all SSE/SSE2/SSE3 instructions on amd64 (see none/tests/amd64/insn-sse
and insn-sse2).  Running those on QEMU might be a quick and easy first
check for something wrong in the SSE department.  They are not completely
comprehensive but may find obvious arithmetic errors and instruction
decoding errors.
