Update ART for LLVM merge up to r187914.

Removed NoFramePointerElimNonLeaf because this is now only specified via
a function attribute (and thus covered by existing cases).

Switch to llvm::sys::fs::F_* enums.

Remove unused DisableSimplifyLibCalls().

(cherry picked from commit 1961a2716cf02f597f06c27a0850daa2dc917586)
