This uses a C++ template to compute the memcmp size at compile time,
which is important for getting inlined memcmp.
There are 4 different key sizes now:
GE with inlined uniforms: 68 bytes
GE without inlined uniforms: 52 bytes
PS with inlined uniforms: 28 bytes
PS without inlined uniforms: 12 bytes

ps is for the pixel shader, while ge is for VS, TCS, TES, and GS.
si_shader_key: 68 bytes
si_shader_key_ge: 68 bytes
si_shader_key_ps: 28 bytes
The only notable change is that si_shader_select_with_key is changed
to a C++ template. Other changes are trivial.
