Fix Freelook on Linux and add speed reset.

Should fix issue 7692.
Also fixes issue 7147.

I have no idea if these changes will affect Mac or Windows users, so please test.
Update freelook description.
Updated game ini files
Explicitly compile external WX in C++11 mode.

Apparently an update to gcc now requires this.
ARMv7 register cache optimizations.
Enable support for not loading a destination register on FPR cache.
Dump registers if they won't be used later in the block. Stolen from Fiora.
Adds MCR/MRC to the ARMv7 emitter.
Implements block time profiling on ARMv7.

This was interesting implementing.
Our generic QueryPerformanceCounter function on ARMv7 was so slow that profiling a block was impossible.
I waited about five minutes and I couldn't even get a single frame to output.
This instead uses ARMv7's PMU to get cycle counts, which are a relatively minor performance drop in my testing.
One disadvantage of this method is that the kernel can lock us out of using these co-processor registers, but it seems to work on my Jetson board.
Another disadvantage is that we aren't having block times in "real" time but cycles instead, not too big of a deal.

This also removes instruction run counts from profiling because that's just annoying and we don't expose an interface for even getting those results
from our UI.
Changed the hotkeys to 1 and 2. Message in GUI changed to reflect this.

Freelook fixes
Android: Use a PagerTabStrip instead of the ActionBar.

The ActionBar method of doing the tabular layout is deprecated on Android 5.0.
This method alleviates those deprecations while providing the same functionality.
Make freelook hotkeys configurable.
