tcg: Change translator-side labels to a pointer
This is improved type checking for the translators -- it's no longer
possible to accidentally swap arguments to the branch functions.

Note that the code generating backends still manipulate labels as int.

With notable exceptions, the scope of the change is just a few lines
for each target, so it's not worth building extra machinery to do this
change in per-target increments.

Backports commit 42a268c241183877192c376d03bd9b6d527407c7 from qemu

tcg: Put opcodes in a linked list
The previous setup required ops and args to be completely sequential,
and was error prone when it came to both iteration and optimization.

tcg: Introduce tcg_op_buf_count and tcg_op_buf_full
The method by which we count the number of ops emitted
is going to change. Abstract that away into some inlines.

Backports commit fe700adb3db5b028b504423b946d4ee5200a8f2f from qemu.

tcg: Change tcg_global_mem_new_* to take a TCGv_ptr
Thus, use cpu_env as the parameter, not TCG_AREG0 directly.
Update all uses in the translators.

Spl3en 4c3ad139ea (Fix #341) SYSENTER instruction is not properly hooked with uc_hook_add in x86 emulation.
helper_sysenter in qemu/target-i386/seg_helper.c didn't check properly if a call interrupt callback was registred.
It has been fixed by copying the helper_syscall behavior.
