GCC complains: Core.cpp:1449:27: warning: overflow in implicit constant conversion [-Woverflow]
I'm not sure if that's really a problem here, but using the enum type is better
style anyways.

a ClangExpressionDeclMap. Any functions that
require value resolution etc. fail if the
ClangExpressionDeclMap isn't present - which is
exactly what is desired.

- conditionally build mac-specific plugins only on mac (PluginObjectFileMachO, PluginDynamicLoaderDrawinKernel and PluginDynamicLoaderMacOSXDYLD)

Summary:
Added BreakableLineComment, moved common code from
BreakableBlockComment to newly added BreakableComment. As a side-effect of the
rewrite, found another problem with escaped newlines and had to change
code which removes trailing whitespace from line comments not to break after
this patch.

A couple of recently introduced conditional branch patterns
also need to be marked as isCodeGenOnly since they cannot

VerifyDiagnosticConsumer previously would not check that the diagnostic and
its matching directive referenced the same source file. Common practice was
to create directives that referenced other files but only by line number,
and this led to problems such as when the file containing the directive
didn't have enough lines to match the location of the diagnostic in the
other file, leading to bizarre file formatting and other oddities.
This patch causes VerifyDiagnosticConsumer to match source files as well as
line numbers. Therefore, a new syntax is made available for directives, for
example:
// expected-error@file:line {{diagnostic message}}
This extends the @line feature where "file" is the file where the diagnostic
is generated. The @line syntax is still available and uses the current file
for the diagnostic. "file" can be specified either as a relative or absolute
path - although the latter has less usefulness, I think! The #include search
paths will be used to locate the file and if it is not found an error will be
generated.
The new check is not optional: if the directive is in a different file to the
diagnostic, the file must be specified. Therefore, a number of test-cases
have been updated with regard to this.
This closes out PR15613.

IRMemoryMap rather than through its own memory
abstraction. This considerably simplifies the
code, and makes it possible to run the
IRInterpreter multiple times on an already-parsed
expression in the absence of a ClangExpressionDeclMap.
Changes include:
- ClangExpressionDeclMap's interface methods
for the IRInterpreter now take IRMemoryMap
arguments. They are not long for this world,
however, since the IRInterpreter will soon be
working with materialized variables.
- As mentioned above, removed the Memory class
from the IR interpreter altogether. It had a
few functions that remain useful, such as
keeping track of Values that have been placed
in memory, so I moved those into methods on
InterpreterStackFrame.
- Changed IRInterpreter to work with lldb::addr_t
rather than Memory::Region as its primary
currency.
- Fixed a bug in the IRMemoryMap where it did not
report correct address byte size and byte order
if no process was present, because it was using
Target::GetDefaultArchitecture() rather than
Target::GetArchitecture().
- Made IRMemoryMap methods clear the Errors they
receive before running. Having to do this by
hand is just annoying.
The testsuite seems happy with these changes, but
please let me know if you see problems (especially
in use cases without a process).

In the classical (non -polly-codegen-scev) mode, we assume that we can always
recreate PHI nodes during code generation. This is not true. We can only
reconstruct them from the polyhedral information, in case the entire loop of the
PHI node is part of the SCoP and consequently the PHI node was translated in
the polyhedral description.

We now support regions with multiple entries and multiple exits natively.
Regions are not needed to be simplified to single entry and single exit.
We need to XFAIL two test cases as this change increases the scop coverage
and uncoveres two failures in the independent blocks pass. The first failure
will be fixed in a subsequent commit, the second one is in the non-default
-polly-codegen-scev mode and still needs to be fixed.

We currently emit an error message when you try to use thread local
storage on targets that don't support it and testing C++11 thread
locals will trip this. We don't want to xfail the test for all darwin
hosts so add a quick hack to check for darwin10 and disable the
test based on that. Only checking darwin10 because anything earlier
is really old and I don't have a list of what other hosts don't
support tls handy.
Alternate suggestions welcome!

This warning comes with two fixits attached to notes, one for parentheses to

For a parameter in a method like this:

we would return the source range of the type and not include the parameter name.

Also, add a few random extra open projects.
Most of C++ support is done; we don't need the status page anymore. We're
hoping that the C++-related open projects are the only major pieces of
functionality we don't model at this point.

This patch allows the Mips assembler to parse and emit nested
expressions as instruction operands. It also extends the
expansion of memory instructions when an offset is given as
an expression.

When we are in a implementation, we check the global method pool whether there were category
methods with the same selector. If there were none (common case) we don't need to do lookups for
overridden methods again.
Note that for an interface method (if we don't encounter its implementation), it is considered that
it overrides methods that were declared before it, not for category methods introduced after it.
This is tradeoff in favor of performance, since it is expensive to do lookups in case there was a
category, and moving the global method pool to ASTContext (so we can check it) would increase complexity.

This is done by extending ObjCMethodList (which is only used by the global method pool) to have 2 extra bits of information.
We will later take advantage of this info in global method pool for the overridden methods calculation.

Materializer for all expressions that need to
run in the target. This includes the following
changes:
- Removed a bunch of (de-)materialization code
from ClangExpressionDeclMap and assumed the
presence of a Materializer where we previously
had a fallback.
- Ensured that an IRMemoryMap is passed into
ClangExpressionDeclMap::Materialize().
- Fixed object ownership on LLVMContext; it is
now owned by the IRExecutionUnit, since the
Module and the ExecutionEngine both depend on
its existence.
- Fixed a few bugs in IRMemoryMap and the
Materializer that showed up during testing.
