Greg Clayton dc968d1665 Fixed an assert that could cause a crash when there was an 
unrecognized DW_TAG_base_type. Now it is a error printed to
stderr.

Greg Clayton 5f5b2cad48 Fixed an issue that broke expression parsing related to backing up 
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.

Stuart Hastings 3cf5308890 Fix an obscure issue in X86_64 parameter passing: if a tiny byval is 
passed as the fifth parameter, insure it's passed correctly (in R9).

Jakob Stoklund Olesen 52375e6a01 Tweak cross-class coalescing to be more aggressive when the target class is small. 
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.

Greg Clayton e6a9e439d4 Fixed the "mmap" to work on MacOSX/darwin by supplying the correct arguemnts. 
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.

Greg Clayton d495c5340d Added an allocated memory cache to avoid having to allocate memory over and 
over when running JITed expressions. The allocated memory cache will cache 
allocate memory a page at a time for each permission combination and divvy up
the memory and hand it out in 16 byte increments.

Jakob Stoklund Olesen 4edf17d91f Teach LiveInterval::isZeroLength about null SlotIndexes. 
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.
