TypeLoc records for declarations; it should not be necessary to represent it
directly in the type system.
Please complain if you were using these classes and feel you can't replicate
previous functionality using the TypeLoc API.

I can see with the original code was that I forgot that this runs after
type legalization and hence the result type will always be i32. (Custom
legalization of EXTRACT_VECTOR_ELT is only enabled for vector types with
8- and 16-bit elements.)
Regarding the FIXME comment: any information about sign and zero-extension
should be captured by separate extension operations. The DAG combiner should
handle those to produce either VGETLANEu or VGETLANEs, and that seems to be
working now. If there are cases that we're missing, let me know.

CheckSpecializationInstantiationRedecl to check for
redeclarations/instantiations. Also fixes a longstanding issue where
our explicit-instantiation location information wasn't as good as it
could have been.

compile-time error now; moreover, remove the need for an explicit hasInnerType()
call. Thanks to Doug Gregor for the metaprogramming approach.

1. Emit external function type information for all COFF targets since it's
a feature of object format
2. Emit linker directives only for cygming (since this is ld-specific stuff)

In the case where there are no good places to put constants and we fall back
upon inserting unconditional branches to make new blocks, allow all constant
pool references in range of those blocks to put constants there, even if that
means resetting the "high water marks" for those references. This will still
terminate because you can't keep splitting blocks forever, and in the bad
cases where we have to split blocks, it is important to avoid splitting more
than necessary.

as expressions, code for parsing a few arm specific directives (still needs
the MCStreamer calls for these). Some clean up of the operand parsing code
and adding some comments.

identifying the malloc as a non-array malloc. This broke GlobalOpt's optimization of stores of mallocs
to global variables.
The fix is to classify malloc's into 3 categories:
1. non-array mallocs
2. array mallocs whose array size can be determined
3. mallocs that cannot be determined to be of type 1 or 2 and cannot be optimized
getMallocArraySize() returns NULL for category 3, and all users of this function must avoid their
malloc optimization if this function returns NULL.
Eventually, currently unexpected codegen for computing the malloc's size argument will be supported in
isArrayMalloc() and getMallocArraySize(), extending malloc optimizations to those examples.

instantiation redeclaration semantics for function template
specializations and member functions of class template
specializations. Also, record the point of instantiation for
explicit-instantiated functions and static data members.

sets of builtin operators. Currently, it is applied
to '++' and '->*' operators. I need to apply it to others
as well. Also, heuristics need be applied to
BuiltinCandidateTypeSet::AddPointerWithMoreQualifiedTypeVariants.
This is WIP.

specializations. Work in progress; there's more cleanup required to
actually use the new CheckSpecializationInstantiationRedecl checker
uniformly.
llvm-svn: 84185
functions/static data members of class template specializations that
do not have definitions. This is the latter part of [temp.explicit]p4;
the former part still needs more testing.
llvm-svn: 84182
cases where an explicit instantiation requires a definition; the
remainder of these checks will come with the implementation of
paragraph 4 of [temp.explicit].
