Removing the option to require the usage of pthread based on an argument
of the getBuildFlags method in lldbtest.py because it can be specified
by a variable in the makefile for the given test case. Using the
variable in the makefile works in all supported platforms.

Add O_TRUNC when opening file for redirecting stdout and stderr of the
process. It is neccessary because if the file exists then on some
platform the original content is kept while it isn't overwritten by the
new data causing pollution of the saved stdout and stderr.

Two changes are required to compile the tests for android
* Disable the usage of -lpthread as it is included by default on
android
* Add -pie to the linker flags because android only support position
independent executables

Summary:
Symbols::LocateExecutableSymbolFile tries to locate the file in containing the debug info in a
splitdebug configuration. It tries to skip over the original file in its search path, but it was
easily fooled by symlinks. This changes the function to use llvm::sys::fs::equivalent, which can
correctly compare symlinks.
As a side effect, I had to fix one test because the address for the "abort" function resolves on
my system to "__GI_abort" now. With the debug info, the libc on my system contains two symbols
associated with the address of the abort function, and lldb prefers __GI_abort, possibly because
the debug info is associated with it. It would be nice at some point to have it prefer the public
symbol name.

Gather and scatter instructions additionally write to one of the source operands - mask register.
In this case Gather has 2 destination values - the loaded value and the mask.
Till now we did not support code gen pattern for gather - the instruction was generated from
intrinsic only and machine node was hardcoded.
When we introduce the masked_gather node, we need to select instruction automatically,
in the standard way.
I added a flag "hasTwoExplicitDefs" that allows to handle 2 destination operands.
(Some code in the X86InstrFragmentsSIMD.td is commented out, just to split one big
patch in many small patches)

```
Enable MiSyntaxTestCase.test_lldbmi_specialchars test.
All test pass on OS X.

The original commit failed to handle "shift assign" (<<=), which
broke the test mentioned in r228406. This is now fixed and the
test added to the lit tests under SemaOpenCL.
*** Original commit message from r228382 ***
OpenCL: handle shift operator with vector operands
Introduce a number of checks:
1. If LHS is a scalar, then RHS cannot be a vector.
2. Operands must be of integer type.
3. If both are vectors, then the number of elements must match.
Relax the requirement for "usual arithmetic conversions":
When LHS is a vector, a scalar RHS can simply be expanded into a
vector; OpenCL does not require that its rank be lower than the LHS.
For example, the following code is not an error even if the implicit
type of the constant literal is "int".
char2 foo(char2 v) { return v << 1; }
Consolidate existing tests under CodeGenOpenCL, and add more tests
under SemaOpenCL.

Summary:
This change fixes the FIXME that you recently added when you committed
(a modified version of) my patch. When `InstCombine` combines a load and
store of an pointer to those of an equivalently-sized integer, it currently
drops any `!nonnull` metadata that might be present. This change replaces
`!nonnull` metadata with `!range !{ 1, -1 }` metadata instead.

The way cleanups (such as PerformSEHFinally) get emitted is that codegen
generates some initialization code, then calls the cleanup's Emit() with the
insertion point set to a good place, then the cleanup is supposed to emit its
stuff, and then codegen might tack in a jump or similar to where the insertion
point is after the cleanup.
The PerformSEHFinally cleanup tries to just stash away the block it's supposed
to codegen into, and then does codegen later, into that stashed block. However,
after codegen'ing the __finally block, it used to set the insertion point to
the finally's continuation block (where the __finally cleanup goes when its body
is completed after regular, non-exceptional control flow). That's not correct,
as that block can (and generally does) already ends in a jump. Instead,
remember the insertion point that was current before the __finally got emitted,
and restore that.
Fixes two of the crashes in PR22553.

It is possible for the atomic routines to be provided by the compiler without
requiring any additional libraries. Check if that is the case before checking
for a library.
