object.__nonzero__(self) is called to implement truth value testing and the built-in operation bool(),
via a simple delegation to self.IsValid().

Change tests under python_api/lldbutil to utilize this mechanism.

1. We would assume that the length of the string literal token was at least 2
2. We would allocate a buffer with size length-2

And when the stars aligned (one of which would be an invalid source location due to stale PCH)
The length would be 0 and we would try to allocate a 4GB buffer.

Add checks for this corner case and a bunch of asserts.
(We really really should have had an assert for 1.).

Note that there's no test case since I couldn't get one (it was major PITA to reproduce),
maybe later.

For calls returning first-class aggregates, store by element instead of creating aggregate stores in common cases.  This is more friendly to fast-isel.

optimization for abstract classes;  there was a misunderstanding, and
it turns out that there are no kexts which rely on this.

vrev is incorrectly defined in the perfect shuffle table. The ordering is backwards (should be 0x3210 versus 0x1032) which exposed a bug when doing a shuffle on a 4xi16. I've attached a test case.

I have on that's #if 0'ed out, and I don't know why it's failing to
delete the constructor. I'd appreciate if someone familiar with access
control could look into ShouldDeleteDefaultConstructor - thanks.

all register values. There is some junk that was appearing at the end
of the result the 'g' packet (read all register values). This function
was being called in:

bool
GDBRemoteRegisterContext::ReadAllRegisterValues (lldb::DataBufferSP &data_sp)

Then the packet data for the 'G' packet (write all registers) was being 
placed into "data_sp" so the:

bool
GDBRemoteRegisterContext::WriteAllRegisterValues (const lldb::DataBufferSP &data_sp)

could restore it. In attempting to clean up the extra junk at the end of this
packet data, the packet was getting truncated.

The greedy register allocator has live range splitting and register class
inflation, so it can actually fully undo this join, including restoring the
original register classes.

We still don't want to do this for long live ranges, mostly because of the high
register pressure of there are many constrained live ranges overlapping.
