env->error_code is only 32-bits wide, so the high 32 bits of EXITINFO1
are being lost. However, even though saving guest state and restoring
host state must be delayed to do_vmexit, because they might take tb_lock,
it is always possible to write to the VMCB. So do this for the exit
code and EXITINFO1, just like it is already being done for EXITINFO2.

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.
