Support allocation of huge stack frame(>2g) on PPC64.
For ELFv2 ABI on Linux, quoted from the spec 18.104.22.168 General Stack Frame Requirements
There is no maximum stack frame size defined.
On AIX, XL allows such huge frame.

Do we have a practical requirement for such a thing? At the very least, I believe we will need code in FI elimination to handle these absurd frame sizes and the test case should show accesses to the stack both before and after the huge allocation.
