Daniel Malea 294c5e1cc3 Fix a problem with the const_variables test case (another lldb bug remains)
- make the test case step past the location where 'index' is initialized, otherwise its value cannot be printed (verified gcc 4.6/4.7 and recent clang)
- "Couldn't materialize struct" error from LLDB still prevents this test case from passing

Jakob Stoklund Olesen 623d8329e3 Use LiveRangeUpdater instead of mergeIntervalRanges.
Performance is the same, but LiveRangeUpdater has a more flexible
interface.

Jakob Stoklund Olesen 521c708e6e 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.

Michael Liao 7fb39669ef Fix PR15267
- When extloading from a vector with non-byte-addressable element, e.g.
  <4 x i1>, the current logic breaks. Extend the current logic to
  fix the case where the element type is not byte-addressable by loading
  all bytes, bit-extracting/packing each element.

Bill Schmidt 51e7951e24 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.

Daniel Jasper dc7d5817e2 Don't remove blank lines within unwrapped lines.
If the code author decides to put empty lines anywhere into the code we
should treat them equally, i.e. reduce them to the configured
MaxEmptyLinesToKeep.

With this change, we e.g. keep the newline in:
SomeType ST = {
  // First value
  a,

  // Second value
  b
};

Elena Demikhovsky 0ccdd1315b I optimized the following patterns:
sext <4 x i1> to <4 x i64>
 sext <4 x i8> to <4 x i64>
 sext <4 x i16> to <4 x i64>
 
I'm running Combine on SIGN_EXTEND_IN_REG and revert SEXT patterns:
 (sext_in_reg (v4i64 anyext (v4i32 x )), ExtraVT) -> (v4i64 sext (v4i32 sext_in_reg (v4i32 x , ExtraVT)))
 
 The sext_in_reg (v4i32 x) may be lowered to shl+sar operations.
 The "sar" does not exist on 64-bit operation, so lowering sext_in_reg (v4i64 x) has no vector solution.

I also added a cost of this operations to the AVX costs table.

Logan Chien 53c18d8ac7 Fix thumbv5e frame lowering assertion failure.
It is possible that frame pointer is not found in the
callee saved info, thus FramePtrSpillFI may be incorrect
if we don't check the result of hasFP(MF).

Besides, if we enable the stack coloring algorithm, there
will be an assertion to ensure the slot is live.  But in
the test case, %var1 is not live in the prologue of the
function, and we will get the assertion failure.

Note: There is similar code in ARMFrameLowering.cpp.

Manuel Klimek 1998ea2c7e Implements breaking of string literals if they stick out.
An alternative strategy to calculating the break on demand when hitting
a token that would need to be broken would be to put all possible breaks
inside the token into the optimizer.

Currently only supports breaking at spaces; more break points to come.
