Rewrite value numbers directly in the 'Other' LiveInterval which is
moribund anyway. This avoids allocating the OtherAssignments vector.

excluding visibility bits.
Mips specific standalone assembler directive "set at".
This directive changes the general purpose register
that the assembler will use when given the symbolic
register name $at.
This does not include negative testing. That will come
in a future patch.
A side affect of this patch recognizes the different
GPR register names for temporaries between old abi
and new abi so a test case for that is included.

When findReachingDefs() finds that only one value can reach the basic
block, just copy the work list of visited blocks directly into the live
interval.
Sort the block list and use a LiveRangeUpdater to make the bulk add
fast.
When multiple reaching defs are found, transfer the work list to the
updateSSA() work list as before. Also use LiveRangeUpdater in
updateLiveIns() following updateSSA().
This makes live interval analysis more than 3x faster on one huge test
case.

The slot that we're adding/removing the attribute from may not be the same as
the attribute coming in. Make sure that they match up before we try to
add/remove them.

'long' and 'long long' are different for the purposes of mangling.
This caused <rdar://problem/13254874>.

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]);
}

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.

-Change the build_dir variable name to lib_dir
-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.

which allows grouping parens in an abstract-pack-declarator. This was already
mostly implemented, but missed some cases. Add an ExtWarn for use of this
extension until CWG ratifies it.

- 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
