71b3a63e9c ARM: fix Thumb-mode simple_idct_arm 
The alignment directive must obviously precede the label.
This was never noticed in ARM mode since the location is
already aligned there.

5c5e1ea3cd ARM: 4-byte align start of all asm functions 
Due to apprent bugs in the GNU assembler and/or linker, relocations
can be incorrectly processed if the alignment of a Thumb instruction
is changed in the output file compared to the input object.

This fixes crashes in h264 decoding with Thumb enabled. No effect in
ARM mode since everything is 4-byte aligned there.

98f24ecd6c rv34: joint coefficient decoding and dequantization 
Perform dequantization while decoding coefficients instead of performing it
on the entire coefficients buffer.

Since quantized coefficients are very sparse, this usually causes a small
speedup. Speedup of around 1% on Panda board compared to the removed here
neon code. Global speedup is probably around 3%.

8ee2b4672f ARM: add explicit .arch and .fpu directives to asm.S 
This prevents build errors when compiler and assembler default
targets differ.  Ideally each file would declare the highest
level it requires.  This is however not easily possible as it
complicates assembling pre-armv6t2 code in Thumb-2 mode.

HAVE_NEON is used as indicator for ARMv7-A since no other
symbol exists for this and NEON is only available in this
variant.
