Follow up to r133032.

Add a new MVT::untyped.  This will be used in future work for modelling ISA features like register pairs and lists with "interesting" constraints (such as ARM NEON contiguous register lists or even-odd paired registers).  We need to be able to generate these instructions (often from intrinsics), but don't want to have to assign a legal type to them.  Instead, we'll use an "untyped" edge to bypass the type-checking and simply ensure that the register classes match.

This simplifies many of the target description files since it is common
for register classes to be related or contain sequences of numbered
registers.

I have verified that this doesn't change the files generated by TableGen
for ARM and X86. It alters the allocation order of MBlaze GPR and Mips
FGR32 registers, but I believe the change is benign.

Language-design credit goes to a lot of people, but I particularly want
to single out Blaine Garst and Patrick Beard for their contributions.

Compiler implementation credit goes to Argyrios, Doug, Fariborz, and myself,
in no particular order.

in order to have its process cleaned up (terminated) upon tearDown is gone for good.
Let's simplify a bunch of Python API test cases.

Patch by Argyrios Kyrtzidis.

llvm-svn: 133093

remove the self.runStarted attribute since the automatic shutdown of processes associated
with the targets are now performed automatically.

llvm-svn: 133092

    bool SBDebugger::DeleteTarget(lldb::SBTarget &target);

which is used in the test tearDown() phase to cleanup the debugger's target list
so that it won't grow larger and larger as test cases are executed.  This is also
a good opportunity to get rid of the arcane requirement that test cases exercising
the Python API must assign the process object to self.process so that it gets
shutdown gracefully.  Instead, the shutdown of the process associated with each
target is now being now automatically.

Also get rid of an API from SBTarget class:

    SBTarget::DeleteTargetFromList(lldb_private::TargetList *list);

Implementation to follow. :)

like the doc's say it should.  Make sure we have a condition before we set up a test whether
we have one, so we only present a "could not parse condition" error if we actually have a condition.

optimizations when emitting calls to the function;  instead those calls may
use faster relocations which require the function to be immediately resolved
upon loading the dynamic object featuring the call.  This is useful when it
is known that the function will be called frequently and pervasively and
therefore there is no merit in delaying binding of the function.

Currently only implemented for x86-64, where it turns into a call through
the global offset table.

Patch by Dan Gohman, who assures me that he's going to add LangRef documentation
for this once it's committed.

Re-apply 133010, with fixes for inline assembler.

Original commit message:
"When an assembler local symbol is used but not defined in a module, a
Darwin assembler wants to issue a diagnostic to that effect."

Added fix to only perform the check when finalizing, as otherwise we're not
done and undefined symbols may simply not have been encountered yet.

Passes "make check" and a self-host check on Darwin.

Use isAnyComplexType here so we don't pass complex numbers into the aggregate handling code; found by inspection.

Note that this actually changes code generation, and someone who
understands this target better should check the changes.

- R12Q is now allocatable. I think it was omitted from the allocation
  order by mistake since it isn't reserved. It as apparently used as a
  GOT pointer sometimes, and it should probably be reserved if that is
  the case.

- The GR64 registers are allocated in a different order now. The
  register allocator will automatically put the CSRs last. There were
  other changes to the order that may have been significant.

The test fix is because r0 and r1 swapped places in the allocation order.

- llvm.dbg.declare already receives line number information from ParmDecl
- Additional extra stoppoint messes up gdb's understanding of where function body starts.

Added a test case for handling physreg aliases during pre-RA-sched.
