2.20.1

The comment in tcg-runtime-gvec.c about CONFIG_VECTOR16 says that

tcg-op-gvec.c has eliminated size 8 vectors, and only passes on

multiples of 16. This may have been true of the first few operations,

but is not true of all operations.

In particular, multiply, shift by scalar, and compare of 8- and 16-bit

elements are not expanded inline if host vector operations are not

supported.

For an x86_64 host that does not support AVX, this means that we will

fall back to the helper, which will attempt to use SSE instructions,

which will SEGV on an invalid 8-byte aligned memory operation.

This patch simply removes the CONFIG_VECTOR16 code and configuration

without further simplification.
