Benjamin Kramer 29f9a00732 CodeGen: Hoist check from recursive function to its only callsite. 
Suggested by Roman Divacky.

Benjamin Kramer 46cbe77b49 CodeGen: When emitting stores for an initializer, only emit a GEP if we really need the store. 
This avoids emitting many dead GEPs for large zero-initialized arrays.

Manuel Klimek de06338a08 This is a temporary solution until we have a better way to 
parse doxygen comments for macros with libclang.

I'm not entirely happy about this script, but as it saves
a lot of work in keeping the docs up to date with the
actual code I think checking it in makes sense.

Jordan Rose 561919e5bd [analyzer] Don't inline constructors for objects allocated with operator new. 
Because the CXXNewExpr appears after the CXXConstructExpr in the CFG, we don't
actually have the correct region to construct into at the time we decide
whether or not to inline. The long-term fix (discussed in PR12014) might be to
introduce a new CFG node (CFGAllocator) that appears before the constructor.

Tracking the short-term fix in <rdar://problem/12180598>.

Jordan Rose c93183042f [analyzer] Inline constructors for any object with a trivial destructor. 
This allows us to better reason about status objects, like Clang's own
llvm::Optional (when its contents are trivially destructible), which are
often intended to be passed around by value.

We still don't inline constructors for temporaries in the general case.

Alexey Samsonov 034e57a297 Add basic support for .debug_ranges section to LLVM's DebugInfo library. 
This section (introduced in DWARF-3) is used to define instruction address
ranges for functions that are not contiguous and can't be described
by low_pc/high_pc attributes (this is the usual case for inlined subroutines).
The patch is the first step to support fetching complete inlining info from DWARF.
