43dab86bcd opus_pvq_search: Restore the proper use of conditional define and simplify the function name suffix handling. 
Using named define properly documents the code paths.
It also avoids passing additional numbered arguments through
multiple levels of macro templates.

The suffix handling is done by concatenation, like in
other asm functions and avoid having two separate
"cglobal" defines.

3c99523a28 opus_pvq_search: split functions into exactness and only use the exact if its faster 
This splits the asm function into exact and non-exact version. The exact
version is as fast or faster on newer CPUs (which EXTERNAL_AVX_FAST describes
well) whilst the non-exact version is faster than the exact on older CPUs.

Also fixes yasm compilation which doesn't accept !cpuflags(avx) syntax.

This reverts commit 24bb7db4037876c5722b0eecf7412502e7225634.

noise has to after all be sign extended, not zero extended, on tests
other than checkasm.
