Rename target_phys_addr_t to hwaddr

target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are
reserved) and its purpose doesn't match the name (most target_phys_addr_t
addresses are not target specific). Replace it with a finger-friendly,...

Emit debug_insn for CPU_LOG_TB_OP_OPT as well.

For all targets that currently call tcg_gen_debug_insn_start,
add CPU_LOG_TB_OP_OPT to the condition that gates it.

This is useful for comparing optimization dumps, when the
pre-optimization dump is merely noise....

target-sh4: implement addv and subv using TCG

addv and subv helpers implementation is directly copied from the SH4
manual and looks quite complex. It is however possible to explain it
without branches, and is therefore possible to implement it with TCG.

target-sh4: optimize xtrct

The register being 32 bit long, after a shift to the right by 16 bits,
the upper 16 bit are already cleared. There is no need to call ext16u
to clear them.

target-sh4: optimize swap.w

It's possible swap the two 16-bit words of a 32-bit register using a
rotation. If the TCG target doesn't implement rotation, the replacement
code is similar to the previously implemented code.

target-sh4: remove gen_clr_t() and gen_set_t()

gen_clr_t() and gen_set_t() have very few callers and can be remplaced
by a single line. Remove them.

target-sh4: rework exceptions handling

Since commit fd4bab102 PC is restored in case of exception through code
retranslation. While it is clearly the thing to do in case it is not
not known if an helper is going to trigger an exception or not
(e.g. for load/store, FPU, etc.), it just make things slower when the...

target-sh4: cleanup DisasContext

We should avoid accessing env at translation stage, except of course for
static values like the supported features.

Remove variables copied from env in DisasContext and use the TB flags
instead.

Almost dead code.

target-sh4: implement addc and subc using TCG

Now that setcond is available, the addc and subc can easily be
implemented using TCG.
