Adam Langley edcd8fda65 bn/asm/x86[_64]-mont*.pl: complement alloca with page-walking. 
(Imports upstream's adc4f1fc25b2cac90076f1e1695b05b7aeeae501.)

Some OSes, *cough*-dows, insist on stack being "wired" to
physical memory in strictly sequential manner, i.e. if stack
allocation spans two pages, then reference to farmost one can
be punishable by SEGV. But page walking can do good even on
other OSes, because it guarantees that villain thread hits
the guard page before it can make damage to innocent one...
