Mans Rullgard f5f004bc5a x86: cabac: don't load/store context values in asm 
Inspection of compiled code shows gcc handles these fine on its own.
Benchmarking also shows no measurable speed difference.

Removing the remaining cases in get_cabac_bypass_sign_x86() does
cause more substantial changes to the compiled code with uncertain
impact.

Mans Rullgard da4c7cce21 x86: fix build with gcc 4.7 
The upcoming gcc 4.7 has more advanced constant propagation
resulting some inline asm operands becoming constants and thus
emitted as literals, sometimes in contexts where this results
in invalid instructions.

This patch changes the constraints of the relevant operands
to "rm" thus forcing a valid type.  While obviously suboptimal,
this is what older gcc versions already did, and there is no
change to the code generated with these.

Mans Rullgard 5cc2600964 dsputil: create 16/32-bit dctcoef versions of some functions 
High bitdepth H.264 needs 32-bit transform coefficients, whereas
dnxhd does not.  This creates a conflict with the templated
functions operating on DCTELEM data.  This patch adds a field
allowing the caller to choose the element size in dsputil_init()
and adds the required functions.

This macro can cause problems in conjunction with the bitdepth

emulated_edge_mc is a dsputil pointer and should not be called
directly, so there is little reason to keep such a macro.
