LLDB (python bindings) Crashing in lldb::SBDebugger::DeleteTarget(lldb::SBTarget&)

Need to check the validity of (SBTarget&)target passed to SBDebugger::DeleteTarget()
before calling target->Destroy().

ARM targets with NEON units have access to aligned vector loads and
stores that are potentially faster than unaligned operations.

Add support for spilling the callee-saved NEON registers to an aligned
stack area using 16-byte aligned NEON loads and store.

This feature is off by default, controlled by an -align-neon-spills
command line option.

My change r146949 added register clobbers to the eh_sjlj_dispatchsetup pseudo
instruction, but on Thumb1 some of those registers cannot be used.  This
caused massive failures on the testsuite when compiling for Thumb1.  While
fixing that, I noticed that the eh_sjlj_setjmp instruction has a "nofp"
variant, and I realized that dispatchsetup needs the same thing, so I have
added that as well.

This was disabled years ago because of a bug in GCC 4.1, which is
on our "broken compilers" list for other reasons. Saving ~500k
on a clang binary (Release+Asserts) is well worth dropping support
for it.

We currently disable it for shared libraries (where it would bring
the biggest win) because clang is broken (PR11642).

IMPORTANT: If you're doing incremental builds you may get tons of
linker warnings. make clean will fix them.

set of (previously-canonical) declaration IDs to the module file, so
that future AST reader instances that load the module know which
declarations are merged. This is important in the fairly tricky case
where a declaration of an entity, e.g.,

  @class X;

occurs before the import of a module that also declares that
entity. We merge the declarations, and record the fact that the
declaration of X loaded from the module was merged into the (now
canonical) declaration of X that we parsed.
