Eliminate unused C DSP functions at compile time

When compiling with asm enabled there's no point in compiling
C versions of DSP functions that have asm implementations using
instruction sets that the compiler can unconditionally use.

E.g. when compiling with -mssse3 we can remove the C version
of all functions with SSSE3 implementations.

This is accomplished using the compiler's dead code elimination
functionality.

Can be configured using the new 'trim_dsp' meson option, which
by default is enabled when compiling in release mode.
