Don't use a "uintptr_t" for the metadata key, use a "void *". This removes all of the casts that were being used and cleans the code up a bit. Also added the ability to dump the metadata.

Make dynamic type detection faster by using the AST metadata to help out and allow us not to complete types when we don't need to.
After running "purge" on a MacOSX system, the Xcode variables view now populates more than 3x faster with this fix.

Make blocks that capture their containing method's object pointer look like methods of
the containing class so that direct ivar access will work in the expression parser.

This is the first phase of supporting the DW_AT_object_pointer tag. I expanded the decl metadata
so it could hold this information, and then used it to look up unfound names in the object pointer
if it exists. This gets "frame var" to work for unqualified references to ivars captured in blocks.
But the expression parser is ignoring this information still.

Added a mechanism for keeping track of where in
the debug information individual Decls came from.
We've had a metadata infrastructure for a while,
which was intended to solve a problem we've since
dealt with in a different way. (It was meant to
keep track of which definition of an Objective-C
class was the "true" definition, but we now find
it by searching the symbols for the class symbol.)
The metadata is attached to the ExternalASTSource,
which means it has a one-to-one correspondence with
AST contexts.
I've repurposed the metadata infrastructure to
hold the object file and DIE offset for the DWARF
information corresponding to a Decl. There are
methods in ClangASTContext that get and set this
metadata, and the ClangASTImporter is capable of
tracking down the metadata for Decls that have been
copied out of the debug information into the
parser's AST context without using any additional
memory.
To see the metadata, you just have to enable the
expression log:
-
(lldb) log enable lldb expr
-
and watch the import messages. The high 32 bits
of the metadata indicate the index of the object
file in its containing DWARFDebugMap; I have also
added a log which you can use to track that mapping:
-
(lldb) log enable dwarf map
-
This adds 64 bits per Decl, which in my testing
hasn't turned out to be very much (debugging Clang
produces around 6500 Decls in my tests). To track
how much data is being consumed, I've also added a
global variable g_TotalSizeOfMetadata which tracks
the total number of Decls that have metadata in all
active AST contexts.
Right now this metadata is enormously useful for
tracking down bugs in the debug info parser. In the
future I also want to use this information to provide
more intelligent error messages instead of printing
empty source lines wherever Clang refers to the
location where something is defined.

Added ClangExternalASTSourceCommon, a local superclass
for all our external AST sources that lets us associate
arbitrary flags with the types we put into the AST
contexts. Also added an API on ClangASTContext that
allows access to these flags given only an ASTContext
and a type.
Because we don't have access to RTTI, and because at
some point in the future we might encounter external
AST sources that we didn't make (so they don't subclass
ClangExternalASTSourceCommon) I added a magic number
that we check before doing anything else, so that we
can catch that problem as soon as it appears.
