to spawn a thread for each process that is being monitored. Previously
LLDB would spawn a single thread that would wait for any child process which
isn't ok to do as a shared library (LLDB.framework on Mac OSX, or lldb.so on
linux). The old single thread used to call wait4() with a pid of -1 which
could cause it to reap child processes that it shouldn't have.
Re-wrote the way Function blocks are handles. Previously I attempted to keep
all blocks in a single memory allocation (in a std::vector). This made the
code somewhat efficient, but hard to work with. I got rid of the old BlockList
class, and went to a straight parent with children relationship. This new
approach will allow for partial parsing of the blocks within a function.

involved watching for the objective C built-in types in DWARF and making sure
when we convert the DWARF types into clang types that we use the appropriate
ASTContext types.
Added a way to find and dump types in lldb (something equivalent to gdb's
"ptype" command):
image lookup --type <TYPENAME>
This only works for looking up types by name and won't work with variables.
It also currently dumps out verbose internal information. I will modify it
to dump more appropriate user level info in my next submission.
Hookup up the "FindTypes()" functions in the SymbolFile and SymbolVendor so
we can lookup types by name in one or more images.
Fixed "image lookup --address <ADDRESS>" to be able to correctly show all
symbol context information, but it will only show this extra information when
the new "--verbose" flag is used.
Updated to latest LLVM to get a few needed fixes.

lldb_private::Language class into the enumerations header so it can be freely
used by other interfaces.
Added correct objective C class support to the DWARF symbol parser. Prior to
this fix we were parsing objective C classes as C++ classes and now that the
expression parser is ready to call functions we need to make sure the objective
C classes have correct AST types.

I also added new functions to create an Objective C class, ivar and set an objective C superclass. They aren't hooked up in the DWARF parser yet. That is the next step, though I am unsure if I will do this in the DWARF parser or try and do it generically in the existing Record manipulation functions.

SectionType for Section objects for DWARF.
Modified the DWARF plug-in to get the DWARF sections by SectionType so we
can safely abstract the LLDB core from section names for the various object
file formats.
Modified the SectionType definitions for .debug_pubnames and .debug_pubtypes
to use the correct case.

- fixed 3 posix spawn attributes leaks
- fixed us always leaking CXXBaseSpecifier objects when we create class
base classes. Clang apparently copies the base classes we pass in.
Fixed some code formatting in ClangASTContext.cpp.

intelligently. The four name types we currently have are:
eFunctionNameTypeFull = (1 << 1), // The function name.
// For C this is the same as just the name of the function
// For C++ this is the demangled version of the mangled name.
// For ObjC this is the full function signature with the + or
// - and the square brackets and the class and selector
eFunctionNameTypeBase = (1 << 2), // The function name only, no namespaces or arguments and no class
// methods or selectors will be searched.
eFunctionNameTypeMethod = (1 << 3), // Find function by method name (C++) with no namespace or arguments
eFunctionNameTypeSelector = (1 << 4) // Find function by selector name (ObjC) names
this allows much more flexibility when setting breakoints:
(lldb) breakpoint set --name main --basename
(lldb) breakpoint set --name main --fullname
(lldb) breakpoint set --name main --method
(lldb) breakpoint set --name main --selector
The default:
(lldb) breakpoint set --name main
will inspect the name "main" and look for any parens, or if the name starts
with "-[" or "+[" and if any are found then a full name search will happen.
Else a basename search will be the default.
Fixed some command option structures so not all options are required when they
shouldn't be.
Cleaned up the breakpoint output summary.
Made the "image lookup --address <addr>" output much more verbose so it shows
all the important symbol context results. Added a GetDescription method to
many of the SymbolContext objects for the more verbose output.
