69fc4da360 Add declarations for the sine tables used in wma.c (half window sizes: 128, 
256, 512, 1024 and 2048) to mdct.c. Make them accessible via dsputil.h. Make
wma.c use these shared tables.

46803f4f67 optimize imdct_half: 
remove tmp buffer.
skip fft reinterleave pass, leaving data in a format more convenient for simd.
merge post-rotate with post-reorder.

5eb0f2a425 float_to_int16_interleave: change src to an array of pointers instead of assuming it's contiguous. 
this has no immediate effect, but will allow it to be used in more codecs.

f67a10cd0c Define mm_flags/support to be 0 on architectures where they don't exist. 
Make sure we don't try to set them if that's the case.
This lets dct-test and fft-test build with --disable-mmx on x86, but not yet on ARM.
