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...

w64: Fix data type of next_tb and tcg_qemu_tb_exec

next_tb is the numeric value of a tcg target (= QEMU host) address.

Using tcg_target_ulong instead of unsigned long shows this and makes
the code portable for hosts with an unusual size of long (w64).

The type cast '(long)(next_tb & ~3)' was not needed (casting...

Rename CPUState -> CPUArchState

Scripted conversion:
for file in .[hc] hw/.[hc] hw/kvm/*.[hc] linux-user/*.[hc] linux-user/m68k/*.[hc] bsd-user/*.[hc] darwin-user/*.[hc] tcg/*/*.[hc] target-*/cpu.h; do

w64: Fix data type of parameters for flush_icache_range

flush_icache_range takes two address parameters which must be large
enough to address any address of the host.

For hosts with sizeof(unsigned long) == sizeof(void *), this patch
changes nothing. All currently supported hosts fall into this category....

tci: Make flush_icache_range() inline

This is standard for other tcg targets and improves tci, too.

tcg: Add bytecode generator for tcg interpreter

Unlike other tcg target code generators, this one does not generate
machine code for some cpu. It generates machine independent bytecode
which is interpreted later.

This allows running QEMU on any host.

Interpreted bytecode is slower than direct execution of generated...
