types to their full definitions more than we needed to. This caused an assertion
in the DWARF parser to fire -- which is an indication that we are parsing too much.

breakpoints on inlined functions by name. This involved fixing the DWARF parser
to correctly back up and parse the concrete function when we find inlined
functions by name, then grabbing any appropriate inlined blocks and returning
symbol contexts with the block filled in. After this was fixed, the breakpoint
by name resolver needed to correctly deal with symbol contexts that had the
inlined block filled in in the symbol contexts.

a debug map with DWARF in the .o files due to the attemted shortcut that was
being taken where the global variables were being searched for by looking in
the symbol table. The problem with the symbols in the symbol table is we don't
break apart the symbol names for symbols when they are mangled into basename
and the fully mangled name since this would take a lot of CPU time to chop up
the mangled names and try and find the basenames. The DWARF info typically has
this broken up for us where the basename of the variable is in a the DW_AT_name
attribute, and the mangled name is in the DW_AT_MIPS_linkage_name attribute.
Now we correctly find globals by searching all OSO's for the information so we
can take advantage of this split information.

(while computing user conversion sequences), make sure that a result
of class type is a complete class type. Had we gone through
ActOnCallExpr, this would have happened when we built the CallExpr.

SimplifyAssociativeOrCommutative) "(A op C1) op C2" -> "A op (C1 op C2)",
which previously was only done if C1 and C2 were constants, to occur whenever
"C1 op C2" simplifies (a la InstructionSimplify). Since the simplifying operand
combination can no longer be assumed to be the right-hand terms, consider all of
the possible permutations. When compiling "gcc as one big file", transform 2
(i.e. using right-hand operands) fires about 4000 times but it has to be said
that most of the time the simplifying operands are both constants. Transforms
3, 4 and 5 each fired once. Transform 6, which is an existing transform that
I didn't change, never fired. With this change, the testcase is now optimized
perfectly with one run of instcombine (previously it required instcombine +
reassociate + instcombine, and it may just have been luck that this worked).

expression. This currently takes waaaayyyyy too much time to evaluate. We will
need to look at the expression parser and find ways to optimize the info we
provide and get this to evaluate quicker. I believe the performance issue is
currently related to us always providing a complete C++ class type when asked
about a C++ class which can cause a lot of information to be pulled since all
classes will be fully created (methods, base classes, members, all their
types). We will need to give the classes back the parser and mark them as
having external sources and get parser (Sema) to query us when it needs more
info. This should bring things up to an acceptable level.

cases when getting the clang type:
- need only a forward declaration
- need a clang type that can be used for layout (members and args/return types)
- need a full clang type
This allows us to partially parse the clang types and be as lazy as possible.
The first case is when we just need to declare a type and we will complete it
later. The forward declaration happens only for class/union/structs and enums.
The layout type allows us to resolve the full clang type _except_ if we have
any modifiers on a pointer or reference (both R and L value). In this case
when we are adding members or function args or return types, we only need to
know how the type will be laid out and we can defer completing the pointee
type until we later need it. The last type means we need a full definition for
the clang type.
Did some renaming of some enumerations to get rid of the old "DC" prefix (which
stands for DebugCore which is no longer around).
Modified the clang namespace support to be almost ready to be fed to the
expression parser. I made a new ClangNamespaceDecl class that can carry around
the AST and the namespace decl so we can copy it into the expression AST. I
modified the symbol vendor and symbol file plug-ins to use this new class.
