RegisterPressure: Simplify liveness tracking when lanemasks are not checked.
Split RegisterOperands code that collects defs/uses into a variant with
and without lanemask tracking. This is a bit of code duplication, but
there are enough subtle differences between the two variants that this
seems cleaner (and potentially faster).
This also fixes a problem where lanes where tracked even though
TrackLaneMasks was false. This is part of the fix for
http://llvm.org/PR27106. I will commit the testcase when it is
completely fixed.
