This is a partial step towards merging the HPHP::VM namespace
up into its parent. To keep it reviewable/mergeable I'm not doing
everything at once here, but most of the code I've touched seems
improved. I've drawn an invisible line around the jit, Unit and
its cohort (Class, Func, PreClass, etc.); we'll get back to them
soon.
Make the targetcache the one true home for constants,
so we dont need to (also) insert them all into
VMExecutionContext::m_constants (which is now gone).
By also making "non-volatile" constants persistent, we save
initializing most of them at all in RepoAuthoritative mode.
Post-hphpc, declaring builtins as inline is useless, which obviates the
need for this layer.
This doesn't fully delete the file, because I wanted to keep mindless
parts and use-your-brain parts separate. This is the mindless part. The
remaining functions in noinline.cpp are no-inline wrappers around
(a) a function that isn't defined in an extension, call_user_func_array,
and (b) calling polymorphic is_* functions, which can probably mostly go
away now. But I wanted to exercise more care around those, so they'll
come in a followup diff.
This is the last step to being able to get rid of the c++ code
gen in hphp. "make -Chphp/system" is now a no-op.
I'll rip out the actual c++ generating code as a separate diff.
This change is mostly for FB internal organizational reasons.
Building is not effected beyond the fact that the target now
lands in hphp/hhvm/hhvm rather than src/hhvm/hhvm.
