aad9f50751 Fix build with hardcoded tables 
The recently added dummy rule for missing headers took precedence
over the tablegen rules.  Listing the generated headers explicitly
overrides this.  A cleaner solution would be preferable.

a46b84d120 PPC: convert Altivec FFT to pure assembler 
On PPC a leaf function has a 288-byte red zone below the stack pointer,
sparing these functions the chore of setting up a full stack frame.

When a function call is disguised within an inline asm block, the
compiler might not adjust the stack pointer as required before a
function call, resulting in the red zone being clobbered.

Moving the entire function to pure asm avoids this problem and also
results in somewhat better code.

35d597d556 mpegaudio: call ff_mpegaudiodec_init_mmx() only from float decoder 
The mmx code is floating-point only, and this function does not know
from which decoder it is called.  Without this change, the integer
decoder only "works" because the size of the context struct is smaller
in this case, and the mmx init function writes the function pointer
outside the allocated context.

Fixes issue 2054.

2cbd734a38 Maybe fix threaded mpeg*video encoding 
This allocates per-thread copies of some MpegEncContext.ac_val which
is used concurrently from the encoding threads.

17dc7c7a60 Fix h264/vp8 intra pred on Athlon XP 
Whose idea was it to have a CPU that didn't SIGILL on an invalid instruction?

4148855ee4 Eliminate another redundant instruction in vp56/8 arithcoder 
Necessary because of this GCC bug:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44474
To do this, convert some, but not all (!) of the variables in VP56RangeCoder
into local variables.
If we convert c->high into a local variable, gcc gets the stupids and refuses
to use a conditional move for the unpredictable main branch.

TODO: dispense with this bullshit and write an asm version.

36d6b545a1 CMOV-ify vp56 arithcoder 
This incantation causes gcc 4.3 to generate cmov on x86, a vastly better option
than a completely unpredictable branch.
Hopefully this carries over to newer versions and other CPUs with conditionals.
~5 cycles saved per call on a Core i7.
