+Pull in r219512 from upstream llvm trunk (by Hal Finkel):
+
+  [MiSched] Fix a logic error in tryPressure()
+
+  Fixes a logic error in the MachineScheduler found by Steve Montgomery
+  (and confirmed by Andy). This has gone unfixed for months because the
+  fix has been found to introduce some small performance regressions.
+  However, Andy has recommended that, at this point, we fix this to
+  avoid further dependence on the incorrect behavior (and then
+  follow-up separately on any regressions), and I agree.
+
+  Fixes PR18883.
+
+This fixes a possible "ran out of registers" error when compiling
+www/firefox 45.0 on i386.
+
+Introduced here: http://svnweb.freebsd.org/changeset/base/xxxxxx
