[PATCH] D37405: [safestack] Experimental mode where stack pointer is accessed with a function call.

[Evgenii Stepanov via Phabricator via llvm-commits]

An attempt to inline the safestack accessor function.

To use, add -mllvm -safestack-pointer-address-inline=1.
Function must be called __safestack_pointer_address_inline.
"__attribute__((used)) static" is recommended so the function is not discarded early.
