Jiangning Liu d5db8765d6 Implement global merge optimization for global variables. ... This commit implements two command line switches -global-merge-on-external and -global-merge-aligned, and both of them are false by default, so this optimization is disabled by default for all targets. For ARM64, some back-end behaviors need to be tuned to get this optimization further enabled. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208934 91177308-0d34-0410-b5e6-96231b3b80d8		2014-05-15 23:45:42 +00:00
