I really would have liked to split this patch up, but it would greatly
complicate the lld-core and lld drivers having to deal with both
{Reader,Writer}Option and TargetInfo.

Extending ValueObjectDynamicValue so that it stores a TypeAndOrName instead of a TypeSP.
This change allows us to reflect the notion that a ValueObject can have a dynamic type for which we have no debug information.
Previously, we would coalesce that to the static type of the object, potentially losing relevant information or even getting it wrong.
This fix ensures we can correctly report the class name for Cocoa objects whose types are hidden classes that we know nothing about (e.g. __NSArrayI for immutable arrays).
As a side effect, our --show-types argument to frame variable no longer needs to append custom dynamic type information.

* Fix a typo, s/BeginSourceAction/BeginSourceFile/, so that the documentation
for FrontendAction::BeginSourceFileAction links correctly to BeginSourceFile;
* Add some basic \file documentation for FrontendAction.h;
* More use of "\brief" instead of repeating the name of the entity being
documented;
* Stop using Doxygen-style "///" comments in FrontendAction.cpp, as they were
polluting the documentation for BeginSourceFile;
* Drop incorrect "\see" markup that broke Doxygen's formatting;
* Other minor documentation fixes.

ErrorOr<void> represents an operation that returns nothing, but can still fail.
It should be used in cases where you need the aditional user data that ErrorOr
provides over error_code.

The method PerformCodePlacement was doing too much (i.e. 3x loops, lots of
different checking). This refactoring separates the analysis section of the
method into a separate function while leaving the actual code placement and
analysis preparation in PerformCodePlacement.
*NOTE* Really this part of ObjCARC should be refactored out of the main pass
class into its own seperate class/struct. But, it is not time to make that
change yet though (don't want to make such an invasive change without fixing all
of the bugs first).

- Add list of physical registers clobbered in pseudo atomic insts
Physical registers are clobbered when pseudo atomic instructions are
expanded. Add them in clobber list to prevent DAG scheduler to
mis-schedule them after these insns are declared side-effect free.
- Add test case from Michael Kuperstein <michael.m.kuperstein@intel.com>

the body does not use them and it appears the body has positional parameters.
This can cause unexpected results as in the added test case. As the darwin
version of gas(1) which only supported positional parameters, happened to
ignore the named parameters. Now that we want to support both styles of
macros we issue a warning in this specific case.

Use the AttributeSet when we're talking about more than one attribute. Add a
function that adds a single attribute. No functionality change intended.

This allows users to promote -Wincompatible-pointer-type warnings to
errors but keep those for "discard qualifiers" as warnings (if they
so desire).
Addresses <rdar://problem/13062738>.

This transform converts the usage of null pointer constants (e.g. NULL, 0,
etc.) in legacy C++ code and converts them to use the new C++11 nullptr
keyword.
- Added use-nullptr transform.
- Added C++11 support to the final syntax check. Used ArgumentAdjuster class to
add -std=c++11 option to the command line options.
- Added tests for use-nullptr transform.
- Added tests that exercises both loop-convert and use-nullptr in the source
file.
TODO: There's a known bug when using both -loop-convert and -use-nullptr at the
same time.

Add the x32 environment kind to the triple, and separate the concept of
pointer size and callee save stack slot size, since they're not equal
on x32.

template typename deductions on swap<> (used in string.cpp). Use
decltype(errno) to replicate the type and qualifier information for holding the
errno value. Because errno is expected to be assignable, there is no need to
use typename std::remove_const<decltype(errno)>::type to hold the value.

Changing nextToken() in the UnwrappedLineParser to get the next
non-comment token. This allows us to correctly layout a whole class of
snippets, like:
if /* */(/* */ a /* */) /* */
f() /* */; /* */
else /* */
g();
Fixes a bug in the formatter where we would assume there is a previous
non-comment token.
Also adds the indent level of an unwrapped line to the debug output in
the parser.
