flac dev - Apr 2012 - remove src/libFLAC/ia32 permanently?

Hi:

In my opinion, we should axe all pure asm implementations in 
src/libFLAC/ia32 and the relevant configure options.

Reasons are simple:

- modern compilers plus the use of intrisincs make the code as faster
   as possible, if you need maximum speed I suggest you to build with 
profiling enabled. ;)

- there is no support for x86_64 (that is.. all modern PC ;-) ) or for 
arm (most modern phones and media players)

- AFAIK, those assembler optimizations may be even slower than the C 
code or buggy.

Thoughts ?

Cheers!

No.  It is much faster, measurably.  Anyone who believes the old adage that
compilers outperform humans isn't writing math code or is just a lousy
assembly programmer.

In which system/compiler did you tried it ?

If thats the case, it would be really cool to have a couple
of small benchmark programs in the tests/ directory that show
this.

It also suggests thats its high time we added an x86_64
version of the asm code.

Cheers,
