91a7593526 target-mips: fix user-mode emulation startup 
Running programs with the MIPS user-mode emulator fails during dynamic
loading, as floating-point instructions are not enabled in in
env->hflags.  Move the code for doing so from fpu_init to cpu_reset so
the MIPS_HFLAG_{FPU,F64} setting doesn't get clobbered by cpu_reset
setting env->hflags to MIPS_HFLAG_UM.

The same end can be achieved by swapping the ordering of fpu_init and
cpu_reset in cpu_mips_init, but it seemed better to consolidate the
CONFIG_USER_ONLY code into a single location.

2a6e32dd46 target-mips: make CP0_LLAddr register CPU dependent 
Depending on the CPU, CP0_LLAddr is either read-only or read-write,
and the returned value can be shifted by a variable amount of bits.

c227f0995e Revert "Get rid of _t suffix" 
In the very least, a change like this requires discussion on the list.

The naming convention is goofy and it causes a massive merge problem.  Something
like this _must_ be presented on the list first so people can provide input
and cope with it.

This reverts commit 99a0949b720a0936da2052cb9a46db04ffc6db29.
