fc313c6434 exec/memop: Adding signedness to quad definitions
Renaming defines for quad in their various forms so that their signedness is
now explicit.
Done using git grep as suggested by Philippe, with a bit of hand edition to
keep assignments aligned.

9002ffcb72 tcg: Rename TCGMemOpIdx to MemOpIdx
We're about to move this out of tcg.h, so rename it
as we did when moving MemOp.

be9568b4e0 tcg: Rename helper_atomic_*_mmu and provide for user-only
Always provide the atomic interface using TCGMemOpIdx oi
and uintptr_t retaddr.  Rename from helper_* to cpu_* so
as to (mostly) match the exec/cpu_ldst.h functions, and
to emphasize that they are not callable from TCG directly.

3e8f1628e8 exec: Use cpu_untagged_addr in g2h; split out g2h_untagged
Use g2h_untagged in contexts that have no cpu, e.g. the binary
loaders that operate before the primary cpu is created.  As a
colollary, target_mmap and friends must use untagged addresses,
since they are used by the loaders.

Use g2h_untagged on values returned from target_mmap, as the
kernel never applies a tag itself.

Use g2h_untagged on all pc values.  The only current user of
tags, aarch64, removes tags from code addresses upon branch,
so "pc" is always untagged.

Use g2h with the cpu context on hand wherever possible.

Use g2h_untagged in lock_user, which will be updated soon.

ed69e8314d i386: move TCG cpu class initialization to tcg/
to do this, we need to take code out of cpu.c and helper.c,
and also move some prototypes from cpu.h, for code that is
needed in tcg/xxx_helper.c, and which in turn is part of the
callbacks registered by the class initialization.

Therefore, do some shuffling of the parts of cpu.h that
are only relevant for tcg/, and put them in tcg/helper-tcg.h

For FT0 and similar macros, put them in tcg/fpu-helper.c
since they are used only there.
