I just tried cross-compiling to ARM with the merge-2.066 branch 
and llvm 3.5 and the latter seems to make a bunch of seg faults 
go away. :) rt.minfo passes its tests now, but core.time asserts 
and so does core.internal.convert still.  As for phobos, 3 
modules pass, 46 modules assert- 41 of which assert in one test 
in std.format, not sure why other modules are running tests for 
std.format- only 9 segfault, and 10 are "Aborted," so I'm down to 
3/69 now, but hopefully much easier to fix with less segfaults.

I didn't get this improvement with merge-2.066 and llvm 3.4, so 
it's definitely llvm 3.5 that made the difference, not sure why.
