When we first converted the A32/T32 frontends to use decodetree,
we put the trans* functions for VFP and Neon into their own
separate files, but used the preprocessor to just #include those
files into translate.c. This was a pragmatic arrangement to avoid
having to also rearrange translate.c which had a lot of utility
functions shared between the main integer decode and the VFP/Neon.
However, having translate.c effectively one enormous file with
all of the integer, Neon and VFP decode in it means it can
push the limits of what some compilers can handle (especially
on 32-bit hosts if the compiler has bugs where it uses too much
memory either during optimisation or while generating debug info).
This series breaks out all the translate-*.c.inc into separate
compilation units.
Changes v1->v2:
* rebased on current master (with rth's alignment series in)
* patch 5 has changed because the gen_aa32 functions were all
changed by the alignment patchset
* patch 7: made gen_set_cpsr and gen_set_condexec not inline,
per rth's suggestion
Only patch 5 needs review.
