create a separate tcg/sysemu/fpu_helper.c for the sysemu-only parts.
For user mode, some small #ifdefs remain in tcg/fpu_helper.c
which do not seem worth splitting into their own user-mode module.

The helper_* functions must use GETPC() to unwind from TCG.
The cpu_x86_* functions cannot, and directly calling the
helper_* functions is a bug. Split out new functions that
perform the work and can be used by both.

Change the prefix from "helper" to "do". The former should be
reserved for those functions that are called from TCG; the latter
is in use within the file already for those functions that are
called from the helper functions, adding a "retaddr" argument.

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.
