tcg/mips: Create and use TCG_REG_TB
This vastly reduces the size of code generated for 64-bit addresses.
The code for exit_tb, for instance, where we load a (tagged) pointer
to the current TB, goes from
0x400aa9725c: li v0,64
0x400aa97260: dsll v0,v0,0x10
0x400aa97264: ori v0,v0,0xaa9

0x400aa9726c: j 0x400aa9703c
0x400aa97270: ori v0,v0,0x7083
to
