Enrico Granata be93a35a8a Python commands: 
It is now possible to use 'command alias --python' to define a command name that actually triggers execution of a Python function
 (e.g. command alias --python foo foo_impl makes a command named 'foo' that runs Python function 'foo_impl')
 The Python function foo_impl should have as signature: def foo_impl(debugger, args, stream, dict): where
  debugger is an object wrapping an LLDB SBDebugger
  args is the command line arguments, as an unparsed Python string
  stream is an SBStream that represents the standard output
  dict is an internal utility parameter and should be left untouched
 The function should return None on no error, or an error string to describe any problems

David Chisnall 719a72f34c Add a mechanism for optimisation plugins to register passes that all front ends can use without needing to be aware of the plugin (or the plugin be aware of the front end). 
Before 3.0, I'd like to add a mechanism for automatically loading a set of plugins from a config file.  API suggestions welcome...

Akira Hatanaka 2263c10946 Fix handling of double precision loads and stores when Mips1 is targeted. 
Mips1 does not support double precision loads or stores, therefore two single
precision loads or stores must be used in place of these instructions. This 
patch treats double precision loads and stores as if they are legal
instructions until MCInstLowering, instead of generating the single precision
instructions during instruction selection or Prolog/Epilog code insertion.

Without the changes made in this patch, llc produces code that has the same 
problem described in r137484 or bails out when
MipsInstrInfo::storeRegToStackSlot or loadRegFromStackSlot is called before
register allocation.

Eli Friedman 0ffdf2ea0b Update SimplifyCFG for atomic operations. 
This commit includes a mention of the landingpad instruction, but it's not
changing the behavior around it.  I think the current behavior is correct,
though.  Bill, can you double-check that?

Bob Wilson aecb7501ad Avoid evaluating Neon macro arguments more than once by disabling type checks. 
It turns out that the use of "__extension__" in these macros was disabling
the expected "incompatible pointer" warnings, so these type checks were not
doing anything anyway.  They introduced a serious bug by evaluating some
macro arguments twice, which is a big problem for arguments with side effects.
I'll have to find another way to get the right type checking.  Radar 9947657.
