90b1b9350c arm: add ff_int32_to_float_fmul_array8_neon
Quite a bit faster than int32_to_float_fmul_array8_c calling
ff_int32_to_float_fmul_scalar_neon through FmtConvertContext.
Number of cycles per int32_to_float_fmul_array8 call while decoding
padded.dts on exynos5422:

               before  after   change
cortex-a7:     1270     951    -25%
cortex-a15:     434     285    -34%

checkasm --bench cycle counts:     cortex-a15   cortex-a7
int32_to_float_fmul_array8_c:      1730.4       4384.5
int32_to_float_fmul_array8_neon_c:  571.5       1694.3
int32_to_float_fmul_array8_neon:    374.0       1448.8

Interesting are the differences between
int32_to_float_fmul_array8_neon_c and int32_to_float_fmul_array8_neon.
The former is current behaviour of calling
ff_int32_to_float_fmul_scalar_neon repeatedly from the c function,
The raw numbers differ since checkasm uses different lengths than the
dca decoder.

Don't rely on the fact that an unprefixed label currently exists.

5e826fd65e ARM: set Tag_ABI_align_preserved in all asm files
All our ARM asm preserves alignment so setting this attribute
in a common location is simpler.  This removes numerous warnings
when linking with armcc.
