a55c93e1f5 Improve ASSUME for Clang 
For some reason, the { if(!x)__builtin_unreachable(); } construct does not
provide the same optimization opportunity for Clang (even though the condition
being false would trigger undefined behavior by reaching unreachable code, it
still performs checks and such for the condition potentially being false).
Using __builtin_assume seems to work better.

400ab8766c Adjust the stereo panning front gain 
This gives it a (more) precise -4.5dB gain drop for front-center panned sounds.

09194fd488 Accumulate the B-Format HRTF responses using doubles 
The final result is still truncated to single-precision float, but this should
keep the responses more stable as it accumulates the various inputs.

e619b64175 Don't minimize the HRTF per-response delay 
The reverts both fa9ab9af7c and
79604c3c0e. As helpful as it was for the high
frequencies, the overall response's gain suffered.

414b56edec Initialize COM using the multithreaded apartment 
I honestly have no idea which is the correct (or better) mode to use given the
confusing mess COM is, but CoInitialize uses single-threaded apartments which
seems to be a problem for with at least a couple games in the STALKER series
(the call fails, which causes us to drop back to the DSound backend).

e288c3b44a Fix HRTF HOA coefficients 
ACN8 was accidentally put on ACN7. However, rather than adding the missing
channel of silence, set up the coefficient map to only use the ambisonic
channels that can contribute to output.

91900b0599 Fix misspellings of quadraphonic 
AL_LOKI_quadriphonic is left alone since that is what the extension is called
and what code expects. All other instances have been fixed for consistency.

79eb2ea26e Reduce the gain of front-panned sounds with plain stereo 
Now front-center sounds are attenuated by roughly -4.5dB instead of -3dB. This
will help keep rear-panned sounds from attenuating too much while not making
front-panned also attenuate too much.
