bbdd903c52 Re-commit r72514 and r72516 with a fixed version of BR_CC lowering.
This patch removes some special cases for opcodes and does a bit of 
cleanup.

94a37a41eb NightlyTest: Write "sentdata.txt" files and run the -submit-aux script before
sending data to the server.
 - Otherwise if the server connection fails the external script never runs.

Also, create content before initiating connection to try and decrease time we
are connected to llvm.org.

1c39965342 Remove special cases for more opcodes.
This is basically the end of this series of patches for LegalizeDAG; the 
remaining special cases can't be removed without more infrastructure 
work.  There's a FIXME for each relevant opcode near the beginning of
SelectionDAGLegalize::LegalizeOp.

3b1259bb9f "The instructions MMX_PSADBWrm and MMX_PSADBWrr have opcode 0b11100000 (e0), but
the Intel manual (screenshot) says it should be 0b11110110 (f6).  The existing
encoding causes a disassembly conflict with MMX_PAVGBrm, which really should be
0f e0."

8b944d39b3 Added optimization that narrow load / op / store and the 'op' is a bit twiddling instruction and its second operand is an immediate. If bits that are touched by 'op' can be done with a narrower instruction, reduce the width of the load and store as well. This happens a lot with bitfield manipulation code.
e.g.
orl     $65536, 8(%rax)
=>
orb     $1, 10(%rax)

Since narrowing is not always a win, e.g. i32 -> i16 is a loss on x86, dag combiner consults with the target before performing the optimization.

4a4f767235 Teach SCEVExpander to avoid creating over-indexed GEP indices when
possible. For example, it now emits

  %p.2.ip.1 = getelementptr [3 x [3 x double]]* %p, i64 2, i64 %tmp, i64 1

instead of the equivalent but less obvious

  %p.2.ip.1 = getelementptr [3 x [3 x double]]* %p, i64 0, i64 %tmp, i64 19

72776d2190 Teach BasicAliasAnalysis to understand constant gep indices that fall
beyond their associated static array type.

I believe that this fixes a legitimate bug, because BasicAliasAnalysis
already has code to check for this condition that works for non-constant
indices, however it was missing the case of constant indices. With this
change, it checks for both.

This fixes PR4267, and miscompiles of SPEC 188.ammp and 464.h264.href.

2efc73d5d0 For the new ar --plugin libLLVMgold.so to work we need libLTO linked with
pthreads, otherwise ar complains of unresolved references to pthread_mutex_*.
LTO doesn't actually use pthreads, but ManagedStatic does.

Fix this by linking in LIBS (that contains pthreads) for LTO and gold.
For now this links in more libs than needed (libffi for example), we can figure
out later how to link in those libs per-tool later.

493a3d015c LiveVariables::VarInfo contains an AliveBlocks BitVector, which has as many
entries as there are basic blocks in the function.  LiveVariables::getVarInfo
creates a VarInfo struct for every register in the function, leading to
quadratic space use.  This patch changes the BitVector to a SparseBitVector,
which doesn't help the worst-case memory use but does reduce the actual use in
very long functions with short-lived variables.
