These symbols were showing up as undefined when trying to link programs on
Android. We should match libgcc's behaviour and provide inline definitions
of these on ARM.
It seems unwind.h on ARM/Darwin doesn't provide inline definitions, so we
just declare them for that platform.

Several of the intrinsic headers were using plain non-reserved identifiers.
C++11 17.6.4.3.2 [global.names] p1 reservers names containing a double
begining with an underscore followed by an uppercase letter for any use.
I think I got them all, but open to being corrected. For the most part I
didn't bother updating function-like macro parameter names because I don't
believe they're subject to any such collission - though some function-like
macros already follow this convention (I didn't update them in part because
the churn was more significant as several function-like macros use the double
underscore prefixed version of the same name as a parameter in their
implementation)
