Henrik Gramner ab43beefab x86inc: Drop SECTION_TEXT macro
The .text section is already 16-byte aligned by default on all supported
platforms so `SECTION_TEXT` isn't any different from `SECTION .text`.

Derek Buitenhuis 15748773bf avresample/x86: Switch operand order for mulps
With the forthcoming VEX instruction emulation, mulps
must have only the third operand point to memory, as
this is what vmulps expects.

Justin Ruggles 10e645e9cb lavr: handle clipping in the float to s32 conversion
We cannot clip to INT_MAX because that value cannot be exactly
represented by a float value and ends up overflowing during conversion
anyway. We need to use a slightly smaller float value, which ends up
with slightly inaccurate results for samples which clip or nearly clip,
but it is close enough. Using doubles as intermediates in the conversion
would be more accurate, but it takes about twice as much time.

Diego Biurrun e0c6cce447 x86: Replace checks for CPU extensions and flags by convenience macros
This separates code relying on inline from that relying on external

parameter is not used, but the code is clearer if they match.
