related failures when running 'make check' without LiveVariables with the
verifier enabled. Some of the remaining failures elsewhere may still be fallout
from incorrect updating of LiveIntervals or the few missing cases left in the
two-address pass.

(2xi32) (truncate ((2xi64) bitcast (buildvector i32 a, i32 x, i32 b, i32 y)))
can be folded into a (2xi32) (buildvector i32 a, i32 b).

Such a DAG would cause uneccessary vdup instructions followed by vmovn
instructions.

We generate this code on ARM NEON for a setcc olt, 2xf64, 2xf64. For example, in
the vectorized version of the code below.

double A[N];
double B[N];

void test_double_compare_to_double() {
  int i;
  for(i=0;i<N;i++)
    A[i] = (double)(A[i] < B[i]);
}

ivars should be camel-case and start with an upper-case letter. A few in
TargetLowering were starting with a lower-case letter.

Turns out unnamed bit fields should not be accessed ever in C (C99 section 4.7.8) or C++
(C++11 section 9.6). 

Unrelated to the above, this commit marks TestBitfields as expected-to-fail with GCC as 4.7
has problems with padding... the size of the struct with a uint32_t member is reported as 12
when GCC is used. Clang emits correct code.

 -Set lib_dir to the correct location on Linux
 -Set LD_EXTRAS to the actual lldb library

This handles the cases where the 6-bit splat element is odd, converting
to a three-instruction sequence to add or subtract two splats.  With this
fix, the XFAIL in test/CodeGen/PowerPC/vec_constants.ll is removed.

mostly implemented, but missed some cases. Add an ExtWarn for use of this
extension until CWG ratifies it.

Performance is the same, but LiveRangeUpdater has a more flexible
interface.

llvm-svn: 175645

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.

Adding support for absolute relocations.  This occurs in ELF files when a relocation is given with no name and an undefined section.  The relocation is applied with an address of zero.

- 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.

It is useful to be able to create temporary LiveRange object whose
members are filled in later.
