Even tough we may want to generate a vector load, the address from which to load
still is a scalar. Make sure even if previous address computations may have been
vectorized, that the addresses are also available as scalars.

In preparation for using a binary format for instrumentation based
profiling, explicitly treat the test inputs as text and transform them
before running. This will allow us to leave the checked in files in
human readable format once the instrumentation format is binary.

No functional change.

This was probably a benign bug, since nobody would look at the vbtable
slots that we were filling in.

Summary:
This prevents the discriminator generation pass from triggering if
the DWARF version being used in the module is prior to 4.

Making some public members into private members. This also introduces a bit more const-correctness, and now uses some range-based for loops. No functional changes intended.

Change the command line vector-insertion.ll to explicitly set the neon syntax

Having i128 as a legal type complicates the legalization phase.  v4i32
is already a legal type, so we will use that instead.

This fixes several piglit tests.

SIFixSGPRCopies is smart enough to handle this now.

This patch improves the performance of vector creation in caseiswhere where
several of the lanes in the vector are a constant floating point value. It
also includes new patterns to fold together some of the instructions when the
value is 0.0f. Test cases included.

After some discussions the preferred semantics of

inline always when the compiler can determine
that it it safe to do so.

Previously, SSPBufferSize was assigned the value of the "stack-protector-buffer-size"
attribute after all uses of SSPBufferSize.  The effect was that the default
SSPBufferSize was always used during analysis.  I moved the check for the
attribute before the analysis; now --param ssp-buffer-size= works correctly again.

Still only 32-bit ARM using it at this stage, but the promotion allows
direct testing via opt and is a reasonably self-contained patch on the
way to switching ARM64.

At this point, other targets should be able to make use of it without
too much difficulty if they want. (See ARM64 commit coming soon for an
example).

This reverts r172072.  clang-format used to use DiagnosticEngine to output

it doesn't, so this code is obsolete.

Getting a pointer into a struct at a non-zero offset would try to

Interceptors don't really work on OSX in asan_noinst_test.cc (this is more or less intentional),
so one shouldn't call intercepted functions in this test -- added a comment about this.

After updating to Xcode.5.1.1 LLDB framework stopped to support partial (only for STDIN) pseudo terminal usage in the debugging process.
