catch or repeated filter clauses. Teach instcombine a bunch
of tricks for simplifying landingpad clauses. Currently the
code only recognizes the GNU C++ and Ada personality functions,
but that doesn't stop it doing a bunch of "generic" transforms
which are hopefully fine for any real-world personality function.
If these "generic" transforms turn out not to be generic, they
can always be conditioned on the personality function. Probably
someone should add the ObjC++ personality function. I didn't as
I don't know anything about it.

This helps with porting code from 2.9 to 3.0 as TargetSelect.h changed location,
and if you include the old one by accident you will trigger this assert.

CoreFoundation object-transfer properties audited, and add a #pragma
to cause them to be automatically applied to functions in a particular
span of code. This has to be implemented largely in the preprocessor
because of the requirement that the region be entirely contained in
a single file; that's hard to impose from the parser without registering
for a ton of callbacks.

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.

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:

All register classes are given a lower ID than their sub-classes.
Cliques are ordered alphabetically.
This will be used to simplify some sub-class operations.

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.

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.
