- Remove code which lowers pseudo SETGP01.
- Fix LowerSETGP01. The first two of the three instructions that are emitted to
  initialize the global pointer register now use register $2.
- Stop emitting .cpload directive.

Add a useful error message to "log enable" with the wrong number of arguments, and reject "log enable lldb" which just silently did nothing before.

Empty live ranges represent undef and still get allocated, but they
won't appear in LiveIntervalUnions.

"lldb -a i386" doesn't set the calculator mode correctly if run on a 64 bit system. 

The previous logic always used the current host architecture, not the default architecture. The default arch gets set into a static varaible in lldb_private::Target when an arch is set from the command line:

lldb -a i386

We now use the default arch correctly.

pointer register. 


This is the first of the series of patches which clean up the way global pointer
register is used. The patches will make the following improvements:

- Make $gp an allocatable temporary register rather than reserving it.
- Use a virtual register as the global pointer register and let the register
  allocator decide which register to assign to it or whether spill/reloads are
  needed.
- Make sure $gp is valid at the entry of a called function, which is necessary
  for functions using lazy binding.
- Remove the need for emitting .cprestore and .cpload directives.

Also changed the defaults for SBThread::Step* to not delete extant plans.
Also added some test cases to test more complex stepping scenarios.

A vector should be returned via the hidden pointer argument except if its size
is equal to or smaller than 16-bytes and the target ABI is N32 or N64.

swig 2.0+ seems to default to using PyLongObjects, but the __len__()
method _must_ return a PyIntObject.
