Fix memory unaligned reads

- Unused code
- Was not correct for unaligned memory reads

MemMap: Cleaned up Read32 unaligned memory access.

ARM: Synchronize Citra's SkyEye core with 3dmoo's.

citra-qt: Rewrite disassembly view.

GPU framebuffer emulation improvements

Templates shouldn't be marked as inline if they aren't defined in the header.

Also makes the illogical component order more obvious.

Anonymous structs are not standard C++, hence don't use them.

[build] Search for the git binary in the default msysgit install dir

core: Kill off type redefenitions in armdefs.h

The Git for Windows installer doesn't add the Git binaries to the path
by default. (Due to risk of conflicts with built-in windows commands.)
Unless you have configured your system specially this causes the
scm_rev_gen.js script to fail to find Git.  Added more paths to the
script so that it searches in the default msysgit installation
directory, eliminating the need to set the PATH for most environments.
