For non-address users, Base and Scaled registers are not specially
associated to fit an address mode, so SCEVExpander should apply normal
expansion rules. Otherwise we may sink computation into inner loops
that have already been optimized.

Specifically, @[] and @{} didn't have a type associated with them; we now
use "NSArray *" and "NSDictionary *", respectively. @"" has the type
"NSString *". @(), unfortunately, has type "id", since it (currently) may
be either an NSNumber or an NSString.

Add a test for all the Objective-C at-expression completions.

We already didn't track objects that have delegates or callbacks or
objects that are passed through void * "context pointers". It's a
not-uncommon pattern to release the object in its callback, and so
the leak message we give is not very helpful.

This is explicitly forbidden in C99 6.7.4p3. This is /not/ forbidden in C++,
probably because by default file-scope const/constexpr variables have internal
linkage, while functions have external linkage. There's also the issue of
anonymous namespaces to consider. Nevertheless, there should probably be a
similar warning, since the semantics of inlining a function that references
a variable with internal linkage do not seem well-defined.

There was already a test that it did not fire in type-dependent contexts.
This was already behaving correctly.

Allow SROA to split up an array of vectors into multiple vectors, even when the vectors are dynamically indexed

linkonce linkage. For example, it is not valid to add unnamed_addr.

This also fixes a crash in g++.dg/opt/static5.C.

This probably mostly shows up in bugpoint-generated code.

We only do very limited physreg coalescing now, but we still merge
virtual registers into reserved registers.

Patch extracted from a larger one by the PaX team. I added the testcases
and tightened error handling a bit.

* Converted comments to use \brief to provide summaries;
* Fixed uses of \arg that should be \p;
* Fixed \param [in] [out] to \param [in,out];
* Made minor formatting fixes.

parameter, not when referring to it from elsewhere).

* Escaped @ symbols that shouldn't be interpreted by Doxygen;
* Deleted \param documentation for function parameters that no longer exist;
* Fixed parameter names in \param Doxygen commands;
* Fixed some broken formatting.

(more complete) version in ASTContext.h.

* Add \brief to produce a summary in the Doxygen output;
* Add missing parameter names to \param commands;
* Fix mismatched parameter names for \param commands;
* Add a parameter name so that the \param has a target.
