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.

Fix a bug in PerformEXTRACT_VECTOR_ELTCombine. The code created an ADD SDNode
with two different types, in cases where the index and the ptr had different
types.

Modified ClangUserExpression and ClangUtilityFunction to display the actual
error (if one is available) that made the JIT fail instead of a canned 
response.

Fixed the restoring of all register values when the 'G' packet doesn't work
to use the correct data.

allocate memory a page at a time for each permission combination and divvy up
the memory and hand it out in 16 byte increments.

When instructions are deleted, they leave tombstone SlotIndex entries.
The isZeroLength method should ignore these null indexes.

This causes RABasic to sometimes spill a callee-saved register in the
abi-isel.ll test, so don't run that test with -regalloc=basic.  Prioritizing
register allocation according to spill weight can cause more registers to be
used.
