Richard Smith 9a56882e53 Add driver arguments -ftemplate-depth=N and -fconstexpr-depth=N, with the same
semantics and defaults as the corresponding g++ arguments. The historical g++
argument -ftemplate-depth-N is kept for compatibility, but modern g++ versions
no longer document that option.

Add -cc1 argument -fconstexpr-depth N to implement the corresponding
functionality.

The -ftemplate-depth=N part of this fixes PR9890.

Peter Collingbourne 119cfaa595 Teach the driver about failure result files, which are compilation
output files that are valid regardless of whether the compilation
succeeded or failed (but not if we crash).  Add depfiles to the

Benjamin Kramer 7824360017 Driver: Remove the signal number from the "command failed" diagnostic.
- With the current implementation of sys::Program this always printed "2".

Ted Kremenek 2acedbd417 Refine placement of LangOptions object in CompilerInvocation by adding a new baseclass CompilerInvocationBase with a custom copy constructor. This ensures that whenever the CompilerInvocation object's copy constructor is used we always clone the LangOptions object.

Argyrios Kyrtzidis effdbf55ac [libclang] Indexing API:
-For indexDeclaration, also pass the declaration attributes as an array of cursors.
-Rename CXIndexOpt_OneRefPerFile -> CXIndexOpt_SuppressRedundantRefs, and only pass

Anna Zaks 040ddfedc0 [analyzer] Do not conjure a symbol when we need to propagate taint.
When the solver and SValBuilder cannot reason about symbolic expressions (ex: (x+1)*y ), the analyzer conjures a new symbol with no ties to the past. This helps it to recover some path-sensitivity. However, this breaks the taint propagation.

With this commit, we are going to construct the expression even if we cannot reason about it later on if an operand is tainted.

Also added some comments and asserts.

Ted Kremenek 8cf47df72f Make 'LangOptions' in CompilerInvocation a heap-allocated, reference counted object. I discovered that llvm::RefCountedBase<T> has
a bug where the reference count is copied in the copy constructor, which means that there were cases when the CompilerInvocation
objects created by ASTUnit were actually leaked.  When I fixed that bug locally, it showed that a whole bunch of code assumed
that the LangOptions object that was part of CompilerInvocation was still alive.  By making it heap-allocated and reference counted,
we can keep it around after the CompilerInvocation object goes away.

As part of this change, change CompilerInvocation:getLangOptions() to return a pointer, acting as another clue that this
object may outlive the CompilerInvocation object.

This commit doesn't fix the CompilerInvocation leak itself.  That will come when I commit the fix to llvm::RefCountedBase<T> to
mainline LLVM.

Douglas Gregor c04f644311 When making a suggestion regarding which module to load rather than
preprocess/parse a header, report back with an actual module (which
may be a submodule) rather than just the name of the module.

Douglas Gregor 56c6401306 When we're loading a framework header, first try to turn the framework
into a module. This module can either be loaded from a module map in
the framework directory (which isn't quite working yet) or inferred
from an umbrella header (which does work, and replaces the existing
hack).

Douglas Gregor b65dbfff52 A module with an umbrella header assumes that all of the headers in
the umbrella header's directory and its subdirectories are part of the
module (that's why it's an umbrella). Make sure that these headers are
considered to be part of the module for lookup purposes.

Douglas Gregor 9dc3212f98 Implement (de-)serialization of the buffer contents for an overridden
file in the source manager. This allows us to properly create and use
modules described by module map files without umbrella headers (or
with incompletely umbrella headers). More generally, we can actually
build a PCH file that makes use of  file -> buffer remappings, which
could be useful in libclang in the future.

Douglas Gregor 4332b32c5e When building a module from a module map that isn't simply an umbrella
