target-mips: No MIPS16 support for 4Kc, 4KEc cores

Fix regression introduced by d19954f46dfc262612c30e9534e660e953049487.

4Kc and 4KEc don't support MIPS16.

target-mips: 4Kc, 4KEc cores do not support MIPS16

4Kc, 4KEc cores do not support MIPS16, so not only the
CP0_Config1 had to be fixed (see previous patch),
but also MIPS16 instructions must not be executed.

(Hint from Nathan Froyd, thanks).

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...

target-mips: add mips16 instruction decoding

There's no good way to add this incrementally, so we do it all at once.
The only changes to shared code are in handle_delay_slot. We need to
flip ISAMode when doing a jump-and-exchange. We also need to set
ISAMode the low bit of the target address for jump-to-register....

target-mips: add gen_base_offset_addr

This is a common pattern in existing code. We'll also use it to
implement the mips16 SAVE/RESTORE instructions.

target-mips: split out delay slot handling

Move delay slot handling to common code whose invocation can be
controlled from gen_intermediate_code_internal.
