Johnny Chen b62a3be1a2 Add an accompanying option to the 'frame variable -w' command to, instead of watching the variable,
watch the location pointed to by the variable.  An example,

(lldb) frame variable -w write -x 1 -g g_char_ptr
(char *) g_char_ptr = 0x0000000100100860 ""...
Watchpoint created: WatchpointLocation 1: addr = 0x100100860 size = 1 state = enabled type = w
    declare @ '/Volumes/data/lldb/svn/trunk/test/functionalities/watchpoint/hello_watchlocation/main.cpp:21'

Jim Grosbach efc761a1eb ARM fix encoding of VMOV.f32 and VMOV.f64 immediates.
Encode the immediate into its 8-bit form as part of isel rather than later,
which simplifies things for mapping the encoding bits, allows the removal
of the custom disassembler decoding hook, makes the operand printer trivial,
and prepares things more cleanly for handling these in the asm parser.

Johnny Chen c44e20cec0 Migrate the in_range(symbol, section) and symbol_iter(module, section) utility functions
from lldbutil.py to the lldb.py proper.  The in_range() function becomes a function in
the lldb module.  And the symbol_iter() function becomes a method within the SBModule
called symbol_in_section_iter().  Example:

        # Iterates the text section and prints each symbols within each sub-section.
        for subsec in text_sec:
            print INDENT + repr(subsec)
            for sym in exe_module.symbol_in_section_iter(subsec):
                print INDENT2 + repr(sym)
                print INDENT2 + 'symbol type: %s' % symbol_type_to_str(sym.GetType())

might produce this following output:

Greg Clayton 6c7f56192f Fixed an issue where a lexical block or inlined function might have bad debug
information generated for it. Say we have a concrete function "foo" which
has inlined function "a" which calls another inlined function "b":

    foo
1   {
2       {
            a ()
3           {
                b ()
4               {
                
                }
            }
        }
    }
    
Sometimes we see the compiler generate an address range in the DWARF for "foo"
(block 1 above) as say [0x1000-0x1100). Then the range for "a" is something
like [0x1050-0x1060) (note that it is correctly scoped within the "foo" 
address range). And then we get "b" which is a child of "a", yet the debug
info says it has a range of [0x1060-0x1080) (not contained within "a"). We now
detect this issue when making our blocks and add an extra range to "a".

Also added a new "lldb" logging category named "symbol" where we can find out
about symbol file errors and warnings.

Johnny Chen a9b68f4dd6 Modify the delegation chain from MachThreadList -> MachThread -> DNBArchProtocol so that when
the watchpoint state is changed, not only does the change propagate to all the thread instances,
it also updates a global debug state, if chosen by the DNBArchProtocol derivative.

Once implemented, the DNBArchProtocol derivative, also makes sure that when new thread comes along,
it tries to inherit from the global debug state, if it is valid.

Modify TestWatchpointMultipleThreads.py to test this functionality.
