Chandler Carruth bbb28e7e98 Fix the threshold added in r186434 (a re-apply of r185393) and updaated ... to be a ManagedStatic in r218163 to not be a global variable written and read to from within the innards of SpillPlacement. This will fix a really scary race condition for anyone that has two copies of LLVM running spill placement concurrently. Yikes! This will also fix a really significant compile time hit that r218163 caused because the spill placement threshold read is actually in the *very* hot path of this code. The memory fence on each read was showing up as huge compile time regressions when spilling is responsible for most of the compile time. For example, optimizing sanitized code showed over 50% compile time regressions here. =/ git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@218921 91177308-0d34-0410-b5e6-96231b3b80d8		2014-10-02 22:23:14 +00:00
