TCG/Sparc64: use stack for TCG temps

Use stack instead of temp_buf array in CPUState for TCG temps.

On Sparc64, stack pointer is not aligned but there is a fixed bias of 2047,
so don't try to enforce alignment.

TCG/x86: use TCG_REG_CALL_STACK instead of TCG_REG_ESP

Except for specific cases where the use of %esp changes the encoding of
the instruction, it's cleaner to use TCG_REG_CALL_STACK instead of
TCG_REG_ESP.

TCG: remove broken stack allocation for call arguments

The code for stack allocation for call arguments is way too simplistic
to actually work on targets with non-trivial stack allocation policies,
e.g. ppc64. We've also already allocated TCG_STATIC_CALL_ARGS_SIZE worth...

TCG: fix negative frame offset calculations

size_t is unsigned, so the frame offset calculations can be incorrect for
negative offsets.

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....

tcg: If DEBUG_TCGV, distinguish TCGv_ptr from TCGv_i32/TCGv_i64

When compiling with DEBUG_TCGV enabled, make the TCGv_ptr type distinct
from TCGv_i32/TCGv_i64. This means that using an i32 or i64 TCG op to
manipulate a TCGv_ptr will always be detected at compile time, rather...
