ART: Change main-thread thread paging scheme
Modify the code that ensures we can install a stack guard page into
the main thread.
A recent kernel change means that our previous approach of using a
free pointer does not work. It is important to actually extend the
stack properly. For portability, use a function with a large stack
frame (suggested by and adapted from hboehm).
