1. Update move expanders to convert the CONST_WIDE_INT and CONST_VECTO
operands to vector broadcast from an integer with AVX2.
2. Add ix86_gen_scratch_sse_rtx to return a scratch SSE register which
won't increase stack alignment requirement and blocks transformation by
the combine pass.
A small be
1. Update vec_duplicate to allow to fail so that backend can only allow
broadcasting an integer constant to a vector when broadcast instruction
is available. This can be used by memset expander to avoid vec_duplicate
when loading from constant pool is more efficient.
2. Add vec_duplicate expander
Changes in the v5 patch:
1. Allow AVX with SI/DI broadcast.
2. Add a comment for broadcasting to V64QI and V32HI with AVX512F, but
without AVX512BW.
