Simon Pilgrim ac04923b0f [X86][SSE] Don't duplicate Lower256IntArith functionality in LowerShift. NFC.
LowerShift was using the same code as Lower256IntArith to split 256-bit vectors into 2 x 128-bit vectors, so now we just call Lower256IntArith.

Tobias Grosser b339594f5d CodegenCleanup: Drop -load-combine pass
This pass is not enabled in the default tool chain and currently can run into an
infinite loop, due to other parts of LLVM generating incorrect IR
(http://llvm.org/PR27065) -- which is not executed and consequently does not
seem to disturb other passes.  As this pass is not really needed, we can just
drop it to get our build clean.

This fixes the timeout issues in MultiSource/Benchmarks/MiBench/consumer-jpeg
and MultiSource/Benchmarks/mediabench/jpeg/jpeg-6a/cjpeg for
-polly-position=before-vectorizer -polly-process-unprofitable.. Unfortunately,
we are still left with a miscompile in cjpeg.

Mehdi Amini cb708b265d Query the StringMap only once when creating MDString (NFC)
Summary:
Loading IR with debug info improves MDString::get() from 19ms to 10ms.
This is a rework of D16597 with adding an "emplace" method on the StringMap
to avoid requiring the MDString move ctor to be public.

Mehdi Amini be8a57f9bf Adjust initial size in StringMap constructor to guarantee no grow()
Summary:
StringMap ctor accepts an initialize size, but expect it to be
rounded to the next power of 2. The ctor can handle that directly
instead of expecting clients to round it. Also, since the map will
resize itself when 75% full, take this into account an initialize
a larger initial size to avoid any growth.

Mehdi Amini 05eca80cb8 Fix DenseMap::reserve(): the formula was wrong
Summary:
Just running the loop in the unittests for a few more iterations
(till 48) exhibit that the condition on the limit was not handled
properly in r263522.
Rewrite the test to use a class to count move/copies that happens
when inserting into the map.
Also take the opportunity to refactor the logic to compute the
number of buckets required for a given number of entries in the map.
Use this when constructing a DenseMap with a desired size given to
the constructor (and add a tests for this).

Jim Ingham a1e541bf9f Use Clang's FixItHints to correct expressions with "trivial" mistakes (e.g. "." for "->".)
This feature is controlled by an expression command option, a target property and the
SBExpressionOptions setting.  FixIt's are only applied to UserExpressions, not UtilityFunctions,
those you have to get right when you make them.

This is just a first stage.  At present the fixits are applied silently.  The next step
is to tell the user about the applied fixit.

Duncan P. N. Exon Smith 68f5624356 Bitcode: Stop using MODULE_CODE_METADATA_VALUES
The motivation for MODULE_CODE_METADATA_VALUES was to enable an
-flto=thin scheme where:

 1. First, one function is cherry-picked from a bitcode file.
 2. Later, another function is cherry-picked.
 3. Later, ...
 4. Finally, the metadata needed by all the previous functions is
    loaded.

This was abandoned in favour of:

 1. Calculate the superset of functions needed from a Module.
 2. Link all functions at once.

Delayed metadata reading no longer serves a purpose.  It also adds
a few complication, since we can't count on metadata being properly
parsed when exiting the BitcodeReader.  After discussing with Teresa, we
agreed to remove it.

The code that depended on this was removed/updated in r264326.

Duncan P. N. Exon Smith efe16c8eb4 IR: Stop upgrading !llvm.loop attachments via MDString
Remove logic to upgrade !llvm.loop by changing the MDString tag
directly.  This old logic would check (and change) arbitrary strings
that had nothing to do with loop metadata.  Instead, check !llvm.loop
attachments directly, and change which strings get attached.

Rather than updating the assembly-based upgrade, drop it entirely.  It
has been quite a while since we supported upgrading textual IR.

Sanjay Patel fff7a3d0ef Add utility script to generate checks for opt or llc regression tests
This is an enhancement of the existing update_llc_test_checks.py script.
It adds some of the functionality from the script used in D17999 to make
the IR checking more flexible.

The bad news: 
This actually is 'My First Python Program'. Thus, it's likely that I have
violated all best practices of Python programming if I've made a functional
change from the original program. If you see anything that's obviously 
wrong, please let me know or feel free to fix it. I didn't even read any
documentation...

The good news: 
I tested this on ~10 existing opt/llc regression tests, and it does what 
I hoped for. It produces exact checking for IR regression tests and doesn't
signficantly change the existing llc-with-x86-target asm checking. The opt
tests that were modified in r263667, r263668, r263674, and r263679 are
examples of the expected results, except that this version of the script 
puts the check lines ahead of the IR to follow the existing llc/asm 
behavior.

If there are no complaints/fallout, we should be able to remove the 
original script. Extending this script to be used for non-x86 and clang
regression tests would be the expected follow-up steps.
