7763ffa017 tcg-aarch64: Change all ext variables to TCGType 
We assert that the values for _I32 and _I64 are 0 and 1 respectively.
This will make a couple of functions declared by tcg.c cleaner.

e58eb53413 exec: Split softmmu_defs.h 
The _cmmu helpers can be moved to exec-all.h.  The helpers that are
used from TCG will shortly need access to tcg_target_long so move
their declarations into tcg.h.

This requires minor include adjustments to all TCG backends.
