Fix major regression in RetainCountChecker.  DefaultSummaries were not being used when they were meant to be.  Fixes <rdar://problem/10241614>.

[analyzer] Remove the last dependency on CheckerContext::getNodeBuilder() as well as the method itself.

Checkers should not directly access NodeBuilder, nodes can be created by calling the CheckerContext's generateNode() methods.

merging an lsl #2 that has multiple uses on A9. This shift is free, so there is
no problem merging it in multiple places. Other unprofitable shifts will not be
merged.

[analyzer] OSAtomicChecker implements evalCall in a very invasive way - it essentially simulates inlining of compareAndSwap() by means of setting the NodeBuilder flags and calling ExprEngine directly. 

This commit introduces a new callback just for this checker to unblock checker API cleanup.

For consistency, prefix multiclass template arg names with the
multiclass name followed by "::" to avoid name clashes among
multiclass arguments and other entities in the multiclass.

Add vim highlighting support for multidefs.

Add Emacs font-lock keyword support for multidefs.

Provide documentation for multidefs, explaining in detail how they
work.

Update the MultiPat.td test to create some defs via multidefs.

llvm-svn: 141235

Add a simple test for multidefs.

Process each multidef declared in a multiclass.  Iterate through the
list and instantiate a def in the multiclass for each item, resolving
the list item to the temporary iterator (possibly) used in the
multidef ObjectBody.  We then process each generated def in the normal
way.

llvm-svn: 141233

Add parser support to recognize multidefs.  No processing on the
multidef is done at this point.  The grammar is:

MultiDef = MULTIDEF ObjectName < Value, Declaration, Value > ObjectBody

The first Value must be resolveable to a list and the second Value
must be resolveable to an integer.  The Declaration is a temporary
value used as an iterator to refer to list items during processing.
It may be passed into the ObjectBody where it will be substituted with
the list value used to instantiate each def.

llvm-svn: 141232

Add keyword support for multidefs.

llvm-svn: 141231

Add a set of data structures and members analogous to those used for
multiclass defs.  These will represent a new kind of multiclass def: a
multidef.  The idea behind the multidef is to process a list of items
and create a def record for each one inside the enclosing multiclass.
This allows the user to dynamically create a set of defs based on the
contents of a list.

llvm-svn: 141230

Move the code to instantiate a multiclass def, bind its arguments and
resolve its members into three helper functions.  These will be reused
to support a new kind of multiclass def: a multidef.

While I'm here, fix the related issue with strncmp, add some actual tests for strcmp and strncmp, and start using StringRef::compare for constant folding instead of using strcmp/strncmp so that the optimized IR isn't dependent on the host's implementation of strcmp.

Stop spurious "DW_AT_specification(0x%8.8x) has no decl" warnings that were due to not parsing the function types when the function blocks are made and parsed.

PhysReg operands are not allowed to have sub-register indices at all.

For virtual registers with sub-reg indices, check that all registers in
the register class support the sub-reg index.
