Changes in directory llvm/include/llvm/CodeGen:

LiveIntervals.h updated: 1.12 -> 1.13

Log message:

Fix failing test cases with joined live intervals. It turns out that
when joining we need to check if we overlap with the second interval
or any of its aliases.

Also make joining intervals the default.

Diffs of the changes:  (+2 -0)
