tcg/mips: Fix regression caused by typo (copy + paste bug)

cppcheck reports an error:
qemu/tcg/mips/tcg-target.c:1487: error: Invalid number of character (()

The unpatched code won't compile on mips hosts starting with commit

Delegate setup of TCG temporaries to targets

Delegate TCG temp_buf setup to targets, so that they can use a stack
frame later instead.

cpu-exec.c: avoid AREG0 use

Make functions take a parameter for CPUState instead of relying
on global env. Pass CPUState pointer to TCG prologue, which moves
it to AREG0.

Thanks to Peter Maydell and Laurent Desnogues for the ARM prologue
change.

Revert the hacks to avoid AREG0 use on Sparc hosts....

Use the correct header in the TCG MIPS code to find cacheflush() on OpenBSD.

Use the correct header in the TCG MIPS code to find cacheflush() on OpenBSD
to fix compilation of the MIPS host support for OpenBSD/mips64 based architecures.

tcg arm/mips/ia64: add a comment about retranslation and caches

Add a comment about cache coherency and retranslation, so that people
developping new targets based on existing ones are warned of the issue.

tcg/mips: fix branch target change during code retranslation

TCG on MIPS was trying to avoid changing the branch offset, but didn't
due to a stupid typo. Fix it.

tcg: Make some tcg-target.c routines static.

Both tcg_target_init and tcg_target_qemu_prologue
are unused outside of tcg.c.

tcg: Add TYPE parameter to tcg_out_mov.

Mirror tcg_out_movi in having a TYPE parameter. This allows x86_64
to perform the move at the proper width, which may elide a REX prefix.

Introduce a TCG_TYPE_REG enumerator to represent the "native width"
of the host register, and to distinguish the usage from "pointer data"...

tcp/mips: Change TCG_AREG0 (fp -> s0)

Register fp (frame pointer) is a bad choice for compilations
without optimisation, because the compiler makes heavy use
of this register (so the resulting code crashes).

Register s0 had been used for TCG_AREG1 in earlier releases,...
