*	[Transforms] Do not drop !preserve.access.index metadata	Yonghong Song	2019-08-03	1	-0/+120
	Currently, when a GVN or CSE optimization happens, the llvm.preserve.access.index metadata is dropped. This caused a problem for BPF AbstructMemberOffset phase as it relies on the metadata (debuginfo types). This patch added proper hooks in lib/Transforms to preserve !preserve.access.index metadata. A test case is added to ensure metadata is preserved under CSE. Differential Revision: https://reviews.llvm.org/D65700 llvm-svn: 367769
