Current GCC versions know how to generate these instructions
properly and avoiding inline asm gives better code. The MULH
function for ARMv5 uses the same instruction and is also not
needed any more.
The MLS64 macro remains since negating an input would normally
not be allowed as it would fail for INT_MIN. In our uses, the
inputs never have this value and thus negating is safe.

Prior to ARMv6, the destination registers of the SMULL instruction
must be distinct from the first source register. Marking the
output early-clobber ensures it is allocated unique registers.
This restriction is dropped in ARMv6 and later, so allowing overlap
between input and output registers there might give better code.

This function uses old-style vector operations deprecated in VFPv3.
Some implementations, e.g. Cortex-A9, support them only through
slow software emulation. Cortex-A8 does have this functionality
in hardware, but as it also has NEON, this function is not used
there regardless.

This patch lets e.g. dsputil_init chose dsp functions with respect to
the bit depth to decode. The naming scheme of bit depth dependent
functions is <base name>_<bit depth>[_<prefix>] (i.e. the old
clear_blocks_c is now named clear_blocks_8_c).
Note: Some of the functions for high bit depth is not dependent on the
bit depth, but only on the pixel size. This leaves some room for
optimizing binary size.

make[1]: *** [libavcodec/arm/ac3dsp_armv6.o] Error 1
MOVW is ARMv7 way to load constant:
* movw, or move wide, will move a 16-bit constant into a register,
implicitly zeroing the top 16 bits of the target register.
* movt, or move top, will move a 16-bit constant into the top half
of a given register without altering the bottom 16 bits
To load 32 bit constant, movw lower16; movt upper16; is better than
ldr if available, because:
While this approach takes two instructions, it does not require any
extra space to store the constant so both the movw/movt method and the
ldr method will end up using the same amount of memory. Memory
bandwidth is precious in and the movw/movt approach avoids an extra
read on the data side, not to mention the read could have missed the
cache.
But here it is armv6 optimization, so that we have to use ldr.
