tcg: Remove TCG_TARGET_HAS_GUEST_BASE define

GUEST_BASE support is now supported by all TCG backends, and is
now mandatory. Drop the now-pointless TCG_TARGET_HAS_GUEST_BASE
define (set by every backend) and the error if it is unset.

tcg: remove obsolete jmp op

The TCG jmp operation doesn't really make sense in the QEMU context, it
is unused, it is not implemented by some targets, and it is wrongly
implemented by some others.

This patch simply removes it.

tci: Fix for AREG0 free mode

Support for helper functions with 5 arguments was missing
in the code generator and in the interpreter.

There is no need to pass the constant TCG_AREG0 from the
code generator to the interpreter. Remove that code for
the INDEX_op_qemu_st* opcodes....

tcg: Remove tcg_target_get_call_iarg_regs_count

The TCG targets no longer need individual implementations.

Since commit 6a18ae2d2947532d5c26439548afa0481c4529f9,
'flags' is no longer used in tcg_target_get_call_iarg_regs_count.

The remaining tcg_target_get_call_iarg_regs_count is trivial and only...

tcg: Introduce movcond

Implemented with setcond if the target does not provide
the optional opcode.

Remove unused CONFIG_TCG_PASS_AREG0 and dead code

Now that CONFIG_TCG_PASS_AREG0 is enabled for all targets,
remove dead code and support for !CONFIG_TCG_PASS_AREG0 case.

Remove dyngen-exec.h and all references to it. Although included by
hw/spapr_hcall.c, it does not seem to use it....

tci: don't write zero for reloc in tci_out_label

If tci_out_label is called in the context of tcg_gen_code_search_pc, we
could be overwriting an already patched relocation with zero -- and not
repatch it because the set_label is past search_pc, causing a QEMU crash...

qemu-log: cleanup

Don't use global variables directly but via accessor functions. Rename globals.

Convert macros to functions, add GCC format attributes.

softmmu templates: optionally pass CPUState to memory access functions

Optionally, make memory access helpers take a parameter for CPUState
instead of relying on global env.

On most targets, perform simple moves to reorder registers. On i386,
switch from regparm(3) calling convention to standard stack-based...
