Extend the -fmodule-file option to support the [<name>=]<file> value format.
If the name is omitted, then the old semantics is preserved (the module file
is loaded whether needed or not). If the name is specified, then the mapping
is treated as just another prebuilt module search mechanism, similar to
-fprebuilt-module-path, and the module file is only loaded if actually used
(e.g., via import). With one exception: this mapping also overrides module
file references embedded in other modules (which can be useful if module files
are moved/renamed as often happens during remote compilation).
This override semantics requires some extra work: we now store the module name
in addition to the file name in the serialized AST representation.

Extract the argument forwarding for OpenCL arguments. Make this more
data driven as we are just repeating the argument name and spelling.
This costs a slight bit more memory due to the string duplication, but
makes it easier to follow. It should be possible to forward the
internal string representation from the TableGen data to avoid this.
But, this makes the code simpler to follow for now.

Summary:
Recent changes canonicalized clang_rt library names to refer to
"i386" on all x86 targets. Android historically uses i686.
This change adds a special case to keep i686 in all clang_rt
libraries when targeting Android.

Summary:
An implementation of ubsan runtime library suitable for use in production.
Minimal attack surface.
* No stack traces.
* Definitely no C++ demangling.
* No UBSAN_OPTIONS=log_file=/path (very suid-unfriendly). And no UBSAN_OPTIONS in general.
* as simple as possible
Minimal CPU and RAM overhead.
* Source locations unnecessary in the presence of (split) debug info.
* Values and types (as in A+B overflows T) can be reconstructed from register/stack dumps, once you know what type of error you are looking at.
* above two items save 3% binary size.
When UBSan is used with -ftrap-function=abort, sometimes it is hard to reason about failures. This library replaces abort with a slightly more informative message without much extra overhead. Since ubsan interface in not stable, this code must reside in compiler-rt.

Overriding a method from a virtual base with a covariant return type
consumes a slot from the vftable in the virtual base. This can make it
impossible to implement certain diamond inheritance hierarchies, but we
have to follow along for compatibility in the simple cases.
This patch only affects our vtable dumper and member pointer function
mangling, since all other callers of getMethodVFTableLocation seem to
recompute VBTableIndex instead of using the one in the method location.

Summary:
This adds a test that checks if the using declaration in classes still works as intended with modules.
The motivation for this is that we tried to add a shortcut to `removeDecl` that would skip the removal of declarations from the lookup table if they are hidden. This optimization passed the clang test suite but actually broke the using declaration in combination with -fmodules-local-submodule-visibility. In this mode we hide all decls from other modules such as by chance the parent method, in which case don't remove the parent method from the lookup table and get ambiguous lookup errors. After this patch we now correctly see if this behavior is broken by a patch like this in the test suite.

llvm-svn: 311990
Summary:
Previously, clang-format would try to wrap template string substitutions
by indenting relative to the openening `${`. This helped with
indenting structured strings, such as strings containing HTML, as the
substitutions would be aligned according to the structure of the string.
However it turns out that the overwhelming majority of template string +
substitution usages are for substitutions into non-structured strings,
e.g. URLs or just plain messages. For these situations, clang-format
would often produce very ugly indents, in particular for strings
containing no line breaks:
return `<a href='http://google3/${file}?l=${row}'>${file}</a>(${
row
},${
col
}): `;
This change makes clang-format indent template string substitutions as
if they were string concatenation operations. It wraps +4 on overlong
lines and keeps all operands on the same line:
return `<a href='http://google3/${file}?l=${row}'>${file}</a>(${
row},${col}): `;
While this breaks some lexical continuity between the `${` and `row}`
here, the overall effects are still a huge improvement, and users can
still manually break the string using `+` if desired.

Use llvm::Triple::getArchTypeName() when looking for compiler-rt
libraries, rather than the exact arch string from the triple. This is
more correct as it matches the values used when building compiler-rt
(builtin-config-ix.cmake) which are the subset of the values allowed
in triples.
For example, this fixes an issue when the compiler set for
i686-pc-linux-gnu triple would not find an i386 compiler-rt library,
while this is the exact arch that is detected by compiler-rt. The same
applies to any other i?86 variant allowed by LLVM.
This also makes the special case for MSVC unnecessary, since now i386
will be used reliably for all 32-bit x86 variants.

This patch implements the initial support for refactoring action rules. The
first rule that's supported is a "source change" rule that returns a set of
atomic changes. This patch is based on the ideas presented in my RFC:
http://lists.llvm.org/pipermail/cfe-dev/2017-July/054831.html
The following pieces from the RFC are added by this patch:
- `createRefactoringRule` (known as `apply` in the RFC)
- `requiredSelection` refactoring action rule requirement.
- `selection::SourceSelectionRange` selection constraint.
