of literal addresses.  Also disabled special-cased
generation of certain expression results (especially
casts), substituting the IR interpreter.

greatest hash table format.

process IDs, and thread IDs, but was mainly needed for for the UserID's for
Types so that DWARF with debug map can work flawlessly. With DWARF in .o files
the type ID was the DIE offset in the DWARF for the .o file which is not
unique across all .o files, so now the SymbolFileDWARFDebugMap class will
make the .o file index part (the high 32 bits) of the unique type identifier
so it can uniquely identify the types.

so we don't have to lookup types in a type list by ID.

Changed the DWARF parser to remove the "can externally complete myself" bits
from the type when we are in the process of completing the type itself to
avoid an onslaught of external visible decl requests from the 
clang::ExternalASTSource.

this patch introduces a new command script import command which takes as input a filename for a Python script and imports the module contained in that file. the containing directory is added to the Python path such that dependencies are honored. also, the module may contain an __lldb_init_module(debugger,dict) function, which gets called after importing, and which can somehow initialize the module's interaction with lldb

is evaluated at the stop point to decide whether we should proceed with
the stopping.

FindExternalVisibleDecls and FindExternalLexicalDecls
are marked and given unique IDs, so that all logging
done as part of their execution can be traced back to
the proper call.

Also there was some logging that really wasn't helpful
in most cases so I disabled it unless verbose logging
(log enable -v lldb expr) is enabled.

inserted in commands by using backticks:

(lldb) memory read `$rsp-16` `$rsp+16`
(lldb) memory read  -c `(int)strlen(argv[0])` `argv[0]`

The result of the expression will be inserted into the command as a sort of
preprocess stage where this gets done first. We might need to tweak where this
preprocess stage goes, but it is very functional already.

Added ansi color support to the Debugger::FormatPrompt() so you can use things
like "${ansi.fg.blue}" and "${ansi.bold}" many more. This helps in adding 
colors to your prompts without needing to know the ANSI color code strings.

Removed SBFrame::WatchValue() and SBFrame::WatchLocation() API as a result of that.

Modified the watchpoint related test suite to reflect the change.

Plus replacing WatchpointLocation with Watchpoint throughout the code base.

llvm-svn: 141917

Fixed a case where we might end up trying to parse a type in the DWARF parser for a method whose class isn't currently in the process of completing itself. Currently, methods of a class, must be parsed when the class type that contains the method is asked to complete itself through the clang::ExternalASTSource virtual functions. Now we "do the right thing" by checking if the class is being defined, and if so we parse it, else we tell the class to complete itself so everything happens correctly.

Specifically, the expression parser used to use
functions attached to SymbolContext to do lookups,
but nowadays it searches a ModuleList or Module
directly instead.  These functions had no
remaining clients so I removed them to prevent
bit rot.

I also removed a stray callback function from
ClangExpressionDeclMap.

which had previously been commented out while I tested
it.  It's not fully working yet, but it doesn't break
our testsuite and it's an important piece of
functionality.

Also added some logging to SymbolFileDWARF to help
diagnose entities that are found in a symbol file,
but do not reside in the expected namespace.

context object.  Having it populated and registered
within a single FindExternalVisibleDecls call worked
fine when there was only one call (i.e., when we were
just looking in the global namespace).  

However, now FindExternalVisibleDecls is called for
nested namespaces as well, which means that it is
called not once but many times (once per module in
which the parent namespace appears).  This means that
the namespace mapping is built up across many calls
to the inferior FindExternalVisibleDecls, so I moved
it into a data structure (the search context) that is
shared by all calls.

I also added some logging to make it easier to see
what is happening during a namespace search, and 
cleaned up some existing logging.

Switched over the materialization mechanism (for JIT

found during parsing.
