Igor Kudrin 061d496c51 [Coverage] Prevent detection of false instantiations in case of macro expansion.
The root of the problem was that findMainViewFileID(File, Function)
could return some ID for any given file, even though that file
was not the main file for that function.

This patch ensures that the result of this function is conformed
with the result of findMainViewFileID(Function).

Pavel Labath 7ef36b5c15 Work around a linux libc bug causing a crash in TaskPool
Summary:
Doing a pthread_detach while the thread is exiting can cause crashes or other mischief, so we
make sure the thread stays around long enough. The performance impact of the added
synchronization should be minimal, as the parent thread is already holding a mutex, so I am just
making sure it holds it for a little while longer. It's possible the new thread will block on
this mutex immediately after startup, but it should be unblocked really quickly and some
blocking is unavoidable if we actually want to have this synchronization.

Ulrich Weigand 9521ad2a49 Fix usage of APInt.getRawData for big-endian systems
Recommit modified version of r266311 including build bot regression fix.

This differs from the original r266311 by:

- Fixing Scalar::Promote to correctly zero- or sign-extend value depending
  on signedness of the *source* type, not the target type.

- Omitting a few stand-alone fixes that were already committed separately.

Pavel Labath 5c17454cd6 Make destructor breakpoint location test more resilient
Summary:
The original breakpoint location test was failing for linux, because the compilers here tend to
merge the full-object and subobject destructors even at -O0 (as a result, we are getting only 2
breakpoint locations, and not 4 as the test expected. The fixup in r266164 substantially weakened
the test, as it now did not check whether both kinds of destructors were being found.

Because of these contraints, I have altered the logic of the test. It sets the
breakpoint by name, and then independently verifies that the breakpoint is set on the correct
demangled symbol name (which is not very meaningful since both kinds of destructors demangle to
the same name) *and* the correct symbol address (which is obtained by looking up the mangled
symbol name).

Andrey Bokhanko f7fa634887 [MSVC Compat] Implementation of __unaligned (MS extension) as a type qualifier
This patch implements __unaligned as a type qualifier; before that, it was
modeled as an attribute. Proper mangling of __unaligned is implemented as well.
Some OpenCL code/tests are tangenially affected, as they relied on existing

Eric Fiselier 90fb2baff7 [libcxx] Remove the "reduced-arity-initialization" extension from the uses-allocator constructors
Summary:
A default uses-allocator constructor has been added since that overload was previously provided by the extended constructor.

Since Clang does implicit conversion checking after substitution this constructor has to deduce the allocator_arg_t parameter so that it can prevent the evaluation of "is_default_constructible" if the first argument doesn't match. See http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_defects.html#1391 for more information.

This implements a PDBASTParser and corresponding logic in
SymbolFilePDB to do type lookup by name.  This is just a first
pass and leaves many aspects of type lookup unimplemented, and
just focuses on laying the framework.  With this patch, you should
be able to lookup basic types by name from a PDB.

Full class definitions are not completed yet, we will instead
just return a forward declaration of the class.
