Reorder the calculations to match the series of vector operations in the most recent bqvec code, just in case it's the order of vector calculations that is saving the time rather than the avoidance of std::vector

Thinkpad T540p i5-4330M @2.80GHz with 16GB RAM, plugged in
Arch Linux, gcc 4.8.2
Using sonic-annotator v1.0 (commit:41c4de1e05d8), release build

Debug flags: -g -fPIC
Release flags: -O3 -ffast-math -msse -mfpmath=sse -ftree-vectorize -fPIC

Release flags for qm-dsp also include -fomit-frame-pointer

The input file is 1-channel 16-bit PCM at 44100Hz, duration 0m43.5s.


DEBUG/RELEASE:

commit:ce64d11ef336, release build of Silvet, release build of qm-dsp

real	1m44.456s
user	1m44.343s
sys	0m0.210s

commit:ce64d11ef336, debug build of Silvet, release build of qm-dsp

real	14m16.124s
user	14m16.907s
sys	0m0.217s

commit:ce64d11ef336, release build of Silvet, debug build of qm-dsp

real	1m55.204s
user	1m55.053s
sys	0m0.253s

Subsequent tests use release builds of both.


VAMP FEATURE SUPPRESSION:

commit:7133f78ccbf6, as commit:ce64d11ef336 but with CQ output feature
return commented out

real	1m46.162s
user	1m46.093s
sys	0m0.157s

commit:78a7bf247016, as commit:ce64d11ef336 but with CQ output and FCQ
output feature return commented out

real	1m45.206s
user	1m45.153s
sys	0m0.147s

conclusion: no advantage in removing these


DEBUG PRINTOUTS:

commit:f3bf6503e6c6, as commit:ce64d11ef336 but with debug printouts
removed

real	1m43.744s
user	1m43.657s
sys	0m0.203s

conclusion: obviously we want to remove these eventually, but might as
well keep in during testing


EM ITERATIONS:

commit:5314d3361dfb, as commit:ce64d11ef336 but with only 6 EM
iterations instead of 12

real	0m59.055s
user	0m58.897s
sys	0m0.193s

conclusion: EM dominates the time taken, not CQ or note forming


CQ DECIMATOR CONFIGURATION:

Uncommitted revision (because changes are in CQ subrepo) that is as
commit:ce64d11ef336 but with resampler SNR=30 and BW=0.04 instead of
SNR=60 and BW=0.02

real	1m43.176s
user	1m43.067s
sys	0m0.190s

conclusion: supports the previous test


EM TWEAKS:

commit:a0dedcbfa628, as commit:ce64d11ef336 but with variables hoisted
out of loops and consts added wherever applicable

real	1m44.548s
user	1m44.460s
sys	0m0.183s

conclusion: compiler already knows this stuff

commit:64b08cc12da0, as commit:ce64d11ef336 but with loops merged so
as theoretically to reduce intermediate calculations

real	3m46.969s
user	3m46.850s
sys	0m0.220s

commit:6075e92d63ab, as commit:64b08cc12da0 but with innermost loop
reverted to three loops with simple bodies instead of one with a more
complex body

real	1m44.767s
user	1m44.490s
sys	0m0.190s

commit:97b77e7cb94c, as commit:6075e92d63ab but with templates stored
as doubles instead of floats (doubling the size of the plugin binary)

real	1m40.135s
user	1m39.820s
sys	0m0.230s
