tcg/mips: optimize brcond arg, 0

MIPS has some conditional branch instructions when comparing with zero.
Use them.

tcg/mips: optimize bswap{16,16s,32} on MIPS32R2

bswap operations can be optimized on MIPS32 Release 2 using the ROTR,
WSBH and SEH instructions. We can't use the non-R2 code to implement the
ops due to registers constraints, so don't define the corresponding...

tcg/mips: implement rotl/rotr ops on MIPS32R2

rotr operations can be optimized on MIPS32 Release 2 using the ROTR and
ROTRV instructions. Also implemented rotl operations by subtracting the
shift from 32.

tcg-mips: fix wrong usage of 'Z' constraint

The 'Z' constraint has been introduced to map the zero register. However
when the op also accept a constant, there is no point to accept the zero
register in addition.

tcg/mips: kill warnings in user mode

Recent versions of GCC emit warnings when compiling user mode targets.
Kill them by reordering a bit the #ifdef.

tcg/mips: use TCGArg or TCGReg instead of int

Instead of int, use the correct TCGArg and TCGReg type: TCGReg when
representing a TCG target register, TCGArg when representing the latter
or a constant.

tcg/mips: don't use global pointer

Don't use the global pointer in TCG, in case helpers try access global
variables.

tcg-hppa: Fix broken load/store helpers

The CONFIG_TCG_PASS_AREG0 code for calling ld/st helpers
was not respecting the ABI requirement for 64-bit values
being aligned in registers.

Mirror the ARM port in use of helper functions to marshal
arguments into the correct registers....
