c8252e80eb x86: mlpdsp: avoid taking address of void
This code contains a C array of addresses of labels defined in
inline asm.  To do this, the names must be declared as external
in C.  The declared type does not matter since only the address is
used, and for some reason, the author of the code used the 'void'
type despite taking the address of a void expression being invalid.

Changing the type to char, a reasonable choice since the alignment
of the code labels cannot be known or guaranteed, eliminates gcc
warnings and allows building with suncc.

c318626ce2 x86: rename libavutil/x86_cpu.h to libavutil/x86/asm.h
This puts x86-specific things in the x86/ subdirectory where they
belong.

d2ee495fb2 configure: Drop check for availability of ten assembler operands.
This was done to support gcc 2.95, which is an old legacy compiler
that fails to compile the current codebase anyway.
