whether an expression is a (core) constant expression as a side-effect of
evaluation. This takes us from accepting far too few expressions as ICEs to
accepting slightly too many -- fixes for the remaining cases are coming next.
The diagnostics produced when an expression is found to be non-constant are
currently quite poor (with generic wording but reasonable source locations),
and will be improved in subsequent commits.

types are equivalent.
+ A taint test which tests bitwise operations and which was
triggering an assertion due to presence of the integer to integer cast.

all of the headers below that particular directory. Use umbrella
directories as a clean way to deal with (1) directories/frameworks
that don't have an umbrella header, but don't want to enumerate all of
their headers, and (2) PrivateHeaders, which we never want to
enumerate and want to keep separate from the main umbrella header.
This also eliminates a little more of the "magic" for private headers,
and frameworks in general.

belonged in the Serialization library, it's setting up a compilation,
not just deserializing.
This should fix PR11512, making Serialization actually be layered below
Frontend, a long standing layering violation in Clang.

part of HeaderSearch. This function just normalizes filenames for use
inside of a synthetic include directive, but it is used in both the
Frontend and Serialization libraries so it needs a common home.

diagnostics. Conflating them was highly confusing and makes it harder to
establish a firm layering separation between these two libraries.

umbrella headers in the sense that all of the headers within that
directory (and eventually its subdirectories) are considered to be
part of the module with that umbrella directory. However, unlike
umbrella headers, which are expected to include all of the headers
within their subdirectories, Clang will automatically include all of
the headers it finds in the named subdirectory.
The intent here is to allow a module map to trivially turn a
subdirectory into a module, where the module's structure can mimic the
directory structure.

header to also support umbrella directories. The umbrella directory
for an umbrella header is the directory in which the umbrella header
resides.
No functionality change yet, but it's coming.

in addition to underlying type.
For example, the warning for printf("%zu", 42.0);
changes from "conversion specifies type 'unsigned long'" to "conversion
specifies type 'size_t' (aka 'unsigned long')"
(This is a second attempt after r145697, which got reverted.)

-Allow it to be used with multiple BeginSourceFile/EndSourceFile calls; for this introduce
a "finish" callback method in the DiagnosticConsumer. SDiagsWriter finishes up the serialization
file inside this method.
-Make it independent of any particular DiagnosticsEngine; make it use the SourceManager of the
Diagnostic object.
-Ignore null source ranges.

when we load a module map (module.map) from a directory, also load a
private module map (module_private.map) for that directory, if
present. That private module map can inject a new submodule that
captures private headers.

- Created a new SymExpr type - SymbolCast.
- SymbolCast is created when we don't know how to simplify a NonLoc to
NonLoc casts.
- A bit of code refactoring: introduced dispatchCast to have better
code reuse, remove a goto.
- Updated the test case to showcase the new taint flow.

- Exposes a CXType_Vector type kind for vector types.
- Adds generalized versions of the clang_getArrayElementType and clang_getArraySize functions, named clang_getElementType and clang_getNumElements, which work on array, vector, or complex types.
- Adds additional functions for querying function types. clang_isFunctionTypeVariadic returns true if a function type is variadic. clang_getFunctionCallingConv returns an enumeration value indicating the calling convention of the function type. clang_getNumArgTypes returns the number of static argument types, and clang_getArgType gets the type of an argument.
- Adds a clang_getTypedefDeclUnderlyingType function to get the underlying type from a TypedefDecl cursor.
- Adds a clang_getEnumDeclIntegerType function to get the integer type from an EnumDecl cursor.
- Adds clang_getEnumConstantDeclValue and clang_getEnumConstantDeclUnsignedValue functions to get the value of an EnumConstantDecl as a signed or unsigned long long, respectively.
- Exposes a CXCursor_AsmLabelAttr cursor kind for __asm__("label") attributes.
- Alters clang_getCursorSpelling to return the label value for AsmLabelAttr-kind cursors.

header search will look into the appropriate Headers/PrivateHeaders
subdirectories for named headers.
