Richard Smith a114c46e87 Revert r288626, which reverts r288449. Original commit message:
Recover better from an incompatible .pcm file being provided by -fmodule-file=. We try to include the headers of the module textually in this case, still enforcing the modules semantic rules. In order to make that work, we need to still track that we're entering and leaving the module. Also, if the module was also marked as unavailable (perhaps because it was missing a file), we shouldn't mark the module unavailable -- we don't need the module to be complete if we're going to enter it textually.

This reverts commit r288449.

I believe that this is currently faulty wrt. modules being imported
inside namespaces. Adding these lines to the new test:

  namespace n {
  #include "foo.h"
  }

Makes it break with

  fatal error: import of module 'M' appears within namespace 'n'

However, I believe it should fail with

  error: redundant #include of module 'M' appears within namespace 'n'

I have tracked this down to us now inserting a tok::annot_module_begin
instead of a tok::annot_module_include in
Preprocessor::HandleIncludeDirective() and then later in
Parser::parseMisplacedModuleImport(), we hit the code path for
tok::annot_module_begin, which doesn't set FromInclude of
checkModuleImportContext to true (thus leading to the "wrong"
diagnostic).

Alex Lorenz 8c1b5c9ea9 [Frontend] Fix an issue where a quoted search path is incorrectly
removed as a duplicate header search path

The commit r126167 started passing the First index into RemoveDuplicates, but
forgot to update 0 to First in the loop that looks for the duplicate. This
resulted in a bug where an -iquoted search path was incorrectly removed if you
passed in the same path into -iquote and more than one time into -isystem.

This commit adds a new predefined macro named __OBJC_BOOL_IS_BOOL that describes

the signed character type, otherwise its value is one as the Objective-C boolean

MacOS; without this change, we don't look in the right places for our

Peter Collingbourne 77c89b6958 Bitcode: Decouple block info block state from reader.
As proposed on llvm-dev:
http://lists.llvm.org/pipermail/llvm-dev/2016-October/106630.html

Move block info block state to a new class, BitstreamBlockInfo.
Clients may set the block info for a particular cursor with the
BitstreamCursor::setBlockInfo() method.

At this point BitstreamReader is not much more than a container for an
ArrayRef<uint8_t>, so remove it and replace all uses with direct uses
of memory buffers.

Chandler Carruth a667ace90c Instead of resetting the pointer, or releasing it which was the previous
code, let's just assert that the DiagonsticEngine doesn't own the client
because our constructor took ownership of it and has a std::unique_ptr
that handles deleting it. This seems much more clear -- the release was
harmless but confusing as if there were some memory there it would have
leaked, and the reset was harmless but confusing as if there were some
memory there it would have been double-freed. But in both cases there
was nothing there.

Peter Collingbourne 028eb5a3f8 Bitcode: Change reader interface to take memory buffers.
As proposed on llvm-dev:
http://lists.llvm.org/pipermail/llvm-dev/2016-October/106595.html

This change also fixes an API oddity where BitstreamCursor::Read() would
return zero for the first read past the end of the bitstream, but would
report_fatal_error for subsequent reads. Now we always report_fatal_error
for all reads past the end. Updated clients to check for the end of the
bitstream before reading from it.

I also needed to add padding to the invalid bitcode tests in
test/Bitcode/. This is because the streaming interface was not checking that
the file size is a multiple of 4.

Alexey Bader 0ea075328e [OpenCL] Override supported OpenCL extensions with -cl-ext option
Summary:
This patch adds a command line option '-cl-ext' to control a set of
supported OpenCL extensions. Option accepts a comma-separated list
of extensions prefixed with '+' or '-'.

It can be used together with a target triple to override support for some
extensions:

  // spir target supports all extensions, but we want to disable fp64
  clang -cc1 -triple spir-unknown-unknown -cl-ext=-cl_khr_fp64

Special 'all' extension allows to enable or disable all possible
extensions:

  // only fp64 will be supported
  clang -cc1 -triple spir-unknown-unknown -cl-ext=-all,+cl_khr_fp64

Justin Lebar 5e83dfedb8 Switch SmallSetVector to use DenseSet when it overflows its inline space.
Summary:
SetVector already used DenseSet, but SmallSetVector used std::set.  This
leads to surprising performance differences.  Moreover, it means that
the set of key types accepted by SetVector and SmallSetVector are
quite different!

In order to make this change, we had to convert some callsites that used
SmallSetVector<std::string, N> to use SmallSetVector<CachedHashString, N>
instead.

Hal Finkel 8f96e82cb8 Add an option to save the backend-produced YAML optimization record to a file
The backend now has the capability to save information from optimizations, the
same information that can be used to generate optimization diagnostics but in
machine-consumable form, into an output file. This can be enabled when using
opt (see r282539), and this change enables it when using clang. The idea is
that other tools will be able to consume these files, and perhaps in
combination with the original source code, produce various kinds of
optimization reports for users (and for compiler developers).

We now have at-least two tools that can consume these files:
  * tools/llvm-opt-report
  * utils/opt-viewer

Using the flag -fsave-optimization-record will cause the YAML file to be
generated; the file name will be based on the output file name (if we're using
-c or -S and have an output name), or the input file name. When we're using
CUDA, or some other offloading mechanism, separate files are generated for each
backend target. The output file name can be specified by the user using
-foptimization-record-file=filename.
