Add a LiveRangeUpdater class.
Adding new segments to large LiveIntervals can be expensive because the
LiveRange objects after the insertion point may need to be moved left or
right. This can cause quadratic behavior when adding a large number of
segments to a live range.
The LiveRangeUpdater class allows the LIveInterval to be in a temporary
invalid state while segments are being added. It maintains an internal
gap in the LiveInterval when it is shrinking, and it has a spill area
for new segments when the LiveInterval is growing.
The behavior is similar to the existing mergeIntervalRanges() function,
except it allocates less memory for the spill area, and the algorithm is
turned inside out so the loop is driven by the clients.

Fix PR15155: lost vadd/vsplat optimization.
During lowering of a BUILD_VECTOR, we look for opportunities to use a
vector splat. When the splatted value fits in 5 signed bits, a single
splat does the job. When it doesn't fit in 5 bits but does fit in 6,
and is an even value, we can splat on half the value and add the result
to itself.
This last optimization hasn't been working recently because of improved
constant folding. To circumvent this, create a pseudo VADD_SPLAT that
can be expanded during instruction selection.

ARM NEON: Don't need COPY_TO_REGCLASS in pattern
In my previous commit:
"Merge a f32 bitcast of a v2i32 extractelt
A vectorized sitfp on doubles will get scalarized to a sequence of an
extract_element of <2 x i32>, a bitcast to f32 and a sitofp.
Due to the the extract_element, and the bitcast we will uneccessarily generate
moves between scalar and vector registers."
I added a pattern containing a copy_to_regclass. The copy_to_regclass is
actually not needed.
