Greg Clayton 3ef3fc6462 Fixed an issue where we would return matches for DWARF in the .o files when
the resulting function from the .o file DWARF didn't make it into the final
executable. I recently changed the way FindFunctions() worked in the DWARF
with debug map case that caused regressions in our test suite for dead 
stripped functions. The previous changes allowed us to leverage the powerful 
searching added to the DWARF parser (search by full name, basename, selector, 
or method name), without having to chop up the symbol names from the symbol
table and do any special parsing of the names to extract the basename, 
selector or method. Previously we would look through the symbol table for 
matches first, then try and find the .o file with DWARF for that symbol and
only search those .o files. Now we let the DWARF for the .o file search using
the new search styles, and filter out any functions that didn't make it.

Greg Clayton 57a6b999af Fixed FindFunctions so it works with all the new name types for the DWARF in object files case.

Greg Clayton b0b9fe610a Added support for objective C built-in types: id, Class, and SEL. This
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.

Greg Clayton 9e40956aea Created lldb::LanguageType by moving an enumeration from the
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.

Greg Clayton 0c5cd90d63 Added function name types to allow us to set breakpoints by name more
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.
