e7a6d5f313 Bug fix for crashes when SSE is used on unaligned arrays.
No measureable change in speed. This gave random crashes on Win32
and BeOS. The cause for this bug is that gcc doesn't align the
stackframe. Linux and glibc always ensure this to be true thus
this never affected Linux.

0b52626eb0 Do not read full byte when less than 8 bits are still to be read.
Does not make a difference with any of my samples, but current
code does not make much sense.

fix coverity warning CID: 255 (uninitalized variable used to build tables which arent used, well there is a slight change of a FPU exception maybe ...)
(by michael)
Init simplification and 2% faster wma_decode_block on amd64 with tables use
instead of pow(). (by banan)

the init simplifictaion is not correct its not binary identical
the pow optimization breaks decoding of http://klif-e.mos.net.au/videos/extr.wmv
