This patch moves the define of target access alignment earlier from
target/foo/cpu.h to configure.

accelerator independent MemOp"

target/mips: rationalise softfloat includes 
We should avoid including the whole of softfloat headers in cpu.h and
explicitly include it only where we will be calling softfloat
functions. We can use the -types.h in cpu.h for the few bits that are
global. We also move the restore_snan_bit_mode into internal.h and
include -helpers.h there.

Backports most of commit 24f55a7973278f20f0de21b904851d99d4716263 from
unicorn. Ignores internal core modifications, as this would be
special-casing non-upstreamed behavior.
