Ensure that option -Y also works for expression as it does for frame variable
Also, if the user passes an explicit format specifier when printing a variable, override the summary's decision to hide the value.

This is required for scenarios like this to work:
(lldb) p/x c
(Class) $0 = 0x0000000100adb7f8 NSObject

Previously this would say:
(lldb) p/x c
(Class) $0 = NSObject

ignoring the explicit format specifier

Debug mode: learning to crawl.  I need to set up some tests that actually test that the debug mode is working, but that won't cause problems when debug mode isn't on.  This is my first prototype of such a test.  It should call std::terminate() because it's comparing iterators from different containers.  And std::terminate() is rigged up to exit normally.  If debug mode fails, and doesn't call terminate, then the program asserts.  The test is a no-op if _LIBCPP_DEBUG2 is not defined or is defined to be 0.

This commit updates the PowerPC back-end (PPCInstrInfo.td and
PPCInstr64Bit.td) to use types instead of register classes in
instruction patterns, along the lines of Jakob Stoklund Olesen's
changes in r177835 for Sparc.

Making value objects properly iterable in constructs of the form
[ x for x in value_with_children ]

This would previously cause an endless loop because lacking a proper iterator object, Python will keep calling __getitem__() with increasing values of the index until it gets an IndexError
since SBValue::GetValueForExpressionPath() supports synthetic array members, no array index will ever really cause an IndexError to be raised, hence the endless iteration

class value_iter is an implementation of __iter__() that provides a terminating iterator over a value

- Masking out SBCommandReturnObject::Printf() from the Python layer because SWIG and varargs do not get along well.
It is replaced by a Print("str") call which is equivalent to Printf("%s","str")
- Providing file-like behavior for SBStream with appropriate extension write() and flush() calls, plus documenting that these are only meant and only exist for Python
Documenting the file-like behavior on our website

sure the base register and would-be writeback register don't conflict for
stores.  This was already being done for loads.

Unfortunately, it is rather difficult to create a test case for this issue.  It
was exposed in 450.soplex at LTO and requires unlucky register allocation.

Fix build dependency. Now can say 'make cpp11-migrate' (with cmake anyway) from
a clean build and result will be usable.

to have them appear in the right order.  Instead append all warnings explicitly
to the language flags.  This was already the case for many warnings.  Fixes the
issue of -Wno-maybe-uninitialized not being effective because -Wall was being
placed after it rather than before.

 - using the nsw attribute when the shl / mul is used by a sign test
 - when the shl / mul is compared for (in)equality to zero

Changed isNullOrUndef => IsNullOrUndef and isNoopInstruction => IsNoopInstruction so that all helper functions are named similarly in ObjCARC.h.
