e029f29385 tcg-aarch64: Handle constant operands to and, or, xor 
Handle a simplified set of logical immediates for the moment.

The way gcc and binutils do it, with 52k worth of tables, and
a binary search depth of log2(5334) = 13, seems slow for the
most common cases.

523fdc08cc tcg-aarch64: Simplify tcg_out_ldst_9 encoding 
At first glance the code appears to be using 1's compliment encoding,
a-la AArch32.  Except that the constant is "off", creating a complicated
split field 2's compliment encoding.

Much clearer to just use a normal mask and shift.

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.
