812fde3603 DAG: avoid duplicated truncating for sign extended operand
Summary:
When performing cmp for EQ/NE and the operand is sign extended, we can
avoid the truncaton if the bits to be tested are no less than origianl
bits.

31b07f1445 Think this will fix issues with the error messages generated for malformed-archives.test
in r277177 and added back this test which was deleted in r277196 while
I tracked down these problems.

Changed from constructing Twine's to std::string's as Twine's don't work
across statements.  Also removed a few unneeded Twine() constructions.

Fix the write_escaped() calls to not pass the unintended second argument
fixing the warning on the ld-x86_64-win7 bot.

f396b4c40d [X86] Match PSADBW in straight-line code
Up until now, we only had code to match PSADBW patterns that look like what
comes out of the loop vectorizer - a partial reduction inside the loop body
that gets fed into a horizontal operation in a different basic block.

This adds support for straight-line patterns, like those generated by the
SLP vectorizer.

a3225b0451 [msf] Resubmit "Rename Msf -> MSF".
Previously this change was submitted from a Windows machine, so
changes made to the case of filenames and directory names did
not survive the commit, and as a result the CMake source file
names and the on-disk file names did not match on case-sensitive
file systems.

I'm resubmitting this patch from a Linux system, which hopefully
allows the case changes to make it through unfettered.

Summary:
Error handling in StreamExecutor is based on llvm::Error and
llvm::Expected. This CL sets up the StreamExecutor wrapper classes in
the streamexecutor namespace.

All the other StreamExecutor code makes use of this error handling code,
so this is the first CL for checking in StreamExecutor.

70c80b336b [lld][MachO] Replace some std::string with char* buffers to eliminate mem leaks.
The MachO debug support code (committed in r276935) occasionally needs to
allocate string copies, and was doing so by creating std::strings on a
BumpPtrAllocator. The strings were untracked, so the destructors weren't being
run and we were leaking the memory when the allocator was thrown away. Since
it's easier than tracking the strings, this patch switches the copies to char
buffers allocated directly in the bump-ptr allocator.

12937c361f [LoopUnroll] Include hotness of region in opt remark
LoopUnroll is a loop pass, so the analysis of OptimizationRemarkEmitter
is added to the common function analysis passes that loop passes

overhead should be observed unless -pass-remarks-with-hotness is used.

02d8d054ab Codegen: MachineBlockPlacement Improve probability layout.
The following pattern was being layed out poorly:

              A
             / \
            B   C
           / \ / \
          D   E   ? (Doesn't matter)

Where A->B is far more likely than A->C, and prob(B->D) = prob(B->E)

The current algorithm gives:
A,B,C,E (D goes on worklist)

It does this even if C has a frequency count of 0. This patch
adjusts the layout calculation so that if freq(B->E) >> freq(C->E)
then we go ahead and layout E rather than C. Fallthrough half the time
is better than fallthrough never, or fallthrough very rarely. The
resulting layout is:

A,B,E, (C and D are in a worklist)
