*	[MC] Teach the MachO object writer about N_FUNC_COLD	Vedant Kumar	2019-01-25	1	-0/+3
	N_FUNC_COLD is a new MachO symbol attribute. It's a hint to the linker to order a symbol towards the end of its section, to improve locality. Example: ``` void a1() {} __attribute__((cold)) void a2() {} void a3() {} int main() { a1(); a2(); a3(); return 0; } ``` A linker that supports N_FUNC_COLD will order _a2 to the end of the text section. From `nm -njU` output, we see: ``` _a1 _a3 _main _a2 ``` Differential Revision: https://reviews.llvm.org/D57190 llvm-svn: 352227
