Daniel Dunbar b6b3e50bf3 [tests] Change with_system_lib feature to match what XFAIL lines expect.
- The lit builtin XFAIL handling is more restrictive than what we were
   previously using, and for now I'd rather keep the lit one restrictive.

Reed Kotler c03807a3a5 Fix a problem with dual mips16/mips32 mode. When the underlying processor
has hard float, when you compile the mips32 code you have to make sure
that it knows to compile any mips32 routines as hard float. I need to clean
up the way mips16 hard float is specified but I need to first think through
all the details. Mips16 always has a form of soft float, the difference being
whether the underlying hardware has floating point. So it's not really
necessary to pass the -soft-float to llvm since soft-float is always true
for mips16 by virtue of the fact that it will not register floating point
registers. By using this fact, I can simplify the way this is all handled.

Edwin Vane 0acd502afe cpp11-migrate: Refactor for driver model of operation
Massive simplification of how replacements and file overrides are handled by
the migrator:
* Sources and headers are all treated the same.
* All replacements for a given translation unit are stored in the same
  TranslationUnitReplacements structure.
* Change tracking is updated only from main file; no need for
  propagating "is tracking" flag around.
* Transform base class no longer responsible for applying replacements.
  They are simply stored and main() looks after deduplication and
  application.
* Renamed -yaml-only to -serialize-replacements. Same restrictions apply:
  Can only request one transform. New restriction: formatting cannot also
  be turned on since it's basically a transform.
* If -serialize-replacements is requested, changes to files will not be
  applied on disk.
* Changed behaviour of function generating names for serialized
  replacements: Only the main source file goes into the name of the file
  since a file may contain changes for multiple different files.
* Updated HeaderReplacements LIT test for new serialization behaviour.
  * Replaced old test that ensures replacements are not serialized if
    -serialize-replacements is not provided. New version ensures changes
    are made directly to all files in the translation unit.
* Updated unit tests.
  * Due to major simplification of structures in FileOverrides.h, the
    FileOverridesTest is quite a bit simpler now.

Jordan Rose e600025528 [analyzer] Treat the rvalue of a forward-declared struct as Unknown.
This will never happen in the analyzed code code, but can happen for checkers

UnknownVal is a harmless enough value to get back.

Daniel Jasper 8ddfa8489b clang-format: Enable formatting of protocol buffer definitions.
Almost by accident, clang-format seems to be able to format protocol
buffer definitions (https://code.google.com/p/protobuf/).

The only change is that a space is required between numeric constants
and opening square brackets (for default values). While this might in
theory be used for array subscripts (int val = 4[MyArray]), I have not
seen this pattern in practice much. If this is wrong, we can make this
smarter in the future.

Hans Wennborg 1cc6cce9a6 Revert r188531: "Windows ToolChain: add VS bin dir to PogramPaths"
This never really worked. Even if we find and execute link.exe in the VS bin dir
this way, link.exe wouldn't find the DLLs it needs, libraries, etc.

It also causes trouble when the user has multiple versions of VS installed,
one of them is in the path, but this code finds the other one (PR17041).

Revert until we can fix this properly.

Pavel Labath 58934986f2 Sema: avoid reuse of Exprs when synthesizing operator=
Summary:
Previously, Sema was reusing parts of the AST when synthesizing an assignment
operator, turning it into a AS-dag. This caused problems for the static
analyzer, which assumed an expression appears in the tree only once.

Here I make sure to always create a fresh Expr, when inserting something into
the AST, fixing PR16745 in the process.
