target-i386: compute eflags outside rcl/rcr helper

Always compute EFLAGS first since it is needed whenever
the shift is non-zero, i.e. most of the time. This makes it possible
to remove some writes of CC_OP_EFLAGS to cpu_cc_op and more importantly
removes cases where s->cc_op becomes CC_OP_DYNAMIC. Also, we can...

target-i386: clean up sahf

Discard CC_DST and set s->cc_op immediately after computing EFLAGS.

target-i386: introduce gen_ext_tl

Introduce a function that abstracts extracting an 8, 16, 32 or 64-bit value
with or without sign, generalizing gen_extu and gen_exts.

target-i386: factor setting of s->cc_op handling for string functions

Set it to the appropriate CC_OP_SUBx constant in gen_scas/gen_cmps.
In the repz case it can be overridden to CC_OP_DYNAMIC after generating
the code.

target-i386: drop cc_op argument of gen_jcc1

As in the gen_repz_scas/gen_repz_cmps case, delay setting
CC_OP_DYNAMIC in gen_jcc until after code generation. All of
gen_jcc1/is_fast_jcc/gen_setcc_slow_T0 now work on s->cc_op, which makes
things a bit easier to follow and to patch....

target-i386: move carry computation for inc/dec closer to gen_op_set_cc_op

This ensures the invariant that cpu_cc_op matches s->cc_op when calling
the helpers. The next patches need this because gen_compute_eflags and
gen_compute_eflags_c will take care of setting cpu_cc_op....

target-i386: Split command line parsing out of cpu_x86_register()

In order to instantiate a CPU subtype we will need to know which type,
so move the cpu_model splitting into cpu_x86_init().

Parameters need to be set on the X86CPU instance, so move
cpu_x86_parse_featurestr() into cpu_x86_init() as well....
