x86: Replace checks for CPU extensions and flags by convenience macros
...
This separates code relying on inline from that relying on external
assembly and fixes instances where the coalesced check was incorrect.

lavr: x86: fix ff_conv_fltp_to_flt_6ch function prototypes
...
Changed to match the number of parameters in conv_func_interleave(), which is
how they are called. The change isn't strictly necessary because the 4th
parameter is not used, but the code is clearer if they match.
