AAC LOAS can have new audio config objects in the stream itself. Make sure the decoder reconfigures itself when the first one arrives midstream. Bug-Id: 644 Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

The vector dequantization has a test in a loop preventing effective SIMD implementation. By moving it out of the loop, this loop can be DSPized. Therefore, modify the current DSP implementation. In particular, the DSP implementation no longer has to handle null loop sizes. The decode_hf implementations have following timings: For x86 Arrandale: C SSE SSE2 SSE4 win32: 260 162 119 104 win64: 242 N/A 89 72 The arm NEON optimizations follow in a later patch as external asm. The now unused check for the y modifier in arm inline asm is removed from configure.

Based on a patch from Christophe Gisquet. Unrolling of the m == 0 case avoids a possible use of the uninitilized value sum when s->predictor_history is not set. I failed to find a sample for it. It also reduced the cycle count from 220 to 150 on sandy bridge, x86_64 linux, gcc 4.8.2 compared to his patch.

Timings for Arrandale: C SSE win32: 2108 334 win64: 1152 322 Factorizing the inner loop with a call/jmp is a >15 cycles cost, even with the jmp destination being aligned. Unrolling for ARCH_X86_64 is a 20 cycles gain. Signed-off-by: Janne Grunau <janne-libav@jannau.net>

This change is inspired by x86 asm where it frees a register. Signed-off-by: Janne Grunau <janne-libav@jannau.net>

This also avoids a macro name clash and related warning on ARM.
