*	add __builtin_unpredictable and convert to metadata	Sanjay Patel	2015-09-02	1	-0/+38
	This patch depends on r246688 (D12341). The goal is to make LLVM generate different code for these functions for a target that has cheap branches (see PR23827 for more details): int foo(); int normal(int x, int y, int z) { if (x != 0 && y != 0) return foo(); return 1; } int crazy(int x, int y) { if (__builtin_unpredictable(x != 0 && y != 0)) return foo(); return 1; } Differential Revision: http://reviews.llvm.org/D12458 llvm-svn: 246699
