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.

x86: Use consistent 3dnowext function and macro name suffixes
...
Currently there is a wild mix of 3dn2/3dnow2/3dnowext. Switching to
"3dnowext", which is a more common name of the CPU flag, as reported
e.g. by the Linux kernel, unifies this.

fft: port FFT/IMDCT 3dnow functions to yasm, and disable on x86-64.
...
64-bit CPUs always have SSE available, thus there is no need to compile
in the 3dnow functions. This results in smaller binaries.
