DIEs. Prior to this fix, there was a 1 to 1 mapping.

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.

Added checks to SymbolFileDWARF that restrict symbol
searches when a namespace is passed in.

we don't need to look them up again when materializing.

Switched over the materialization mechanism (for JIT
expressions) and the lookup mechanism (for interpreted
expressions) to use the VariableSP/Symbol that were
found during parsing.

lifetime of ClangExpressionDeclMap.  This allows
ClangExpressionVariables found during parsing to be
queried for their containing namespaces during
expression execution.

Other clients (like ClangFunction) explicitly delete
this state, so they should not result in any memory
leaks.

calls to the FindExternalVisibleDecls function.

FindExternalVisibleDecls was recording whether
it had found generic function symbols in variables
that were local to the function.  Now, however,
multiple calls occur in response to one request
from Clang, since we may be searching across
namespaces.  To support that, I moved the local
variables into a bitfield in NameSearchContext.

of namespaces (only in the modules where they've
been found) for entities inside those namespaces.

For each NamespaceDecl that has been imported into
the parser, we maintain a map containing
[ModuleSP, ClangNamespaceDecl] pairs in the ASTImporter.
This map has one entry for each module in which the
namespace has been found.  When we later scan for an
entity inside a namespace, we search only the modules
in which that namespace was found.

Also made a small whitespace fix in 
ClangExpressionParser.cpp.

to be able to specify the runhook(s) to bring the debug session to a certain state
before running the benchmarking logic.  An example,

./dotest.py -v -t +b -k 'process attach -n Mail' -k 'thread backtrace all' -p TestRunHooksThenSteppings.py

spawns lldb, attaches to the 'Mail' application, does a backtrace for all threads, and then
runs the benchmark to step the inferior multiple times.
