5a534314a8 target/arm: Move feature test functions to their own header 
The feature test functions isar_feature_*() now take up nearly
a thousand lines in target/arm/cpu.h. This header file is included
by a lot of source files, most of which don't need these functions.
Move the feature test functions to their own header file.

d7ec12f83c tcg: Split out tcg init functions to tcg/startup.h 
The tcg/tcg.h header is a big bucket, containing stuff related to
the translators and the JIT backend.  The places that initialize
tcg or create new threads do not need all of that, so split out
these three functions to a new header.
