We already support GR64 <-> VR128 copies.  All of these copies break
partial register dependencies by zeroing the high part of the target
register.

Start stubbing out MCModule and MCAtom, which provide an API for accessing the rich disassembly of a complete object or executable.
These are very much a work in progress, and not really useful yet.

Sometimes register class constraints are trivial, like GR32->GR32_NOSP,
or GPR->rGPR.  Teach InstrEmitter to simply constrain the virtual
register instead of emitting a copy in these cases.

Normally, these copies are handled by the coalescer.  This saves some
coalescer work.

The function will refuse to use a register class with fewer registers
than MinNumRegs.  This can be used by clients to avoid accidentally
increase register pressure too much.

The default value of MinNumRegs=0 doesn't affect how constrainRegClass()
works.

addition the defined OLD_EXC_SYSTEM was not tested with this version.

infrastructure. As this makes the demo no longer a demo, and especially not a 
demo on how to use the llvm exception mechanism, this hack will shortly be 
changed to use the new 3.0 exception infrastructure. However for the time being 
this demo is an example on how to use the AutoUpgrade 
UpgradeExceptionHandling(...) function on < 3.0 exception handling code.

- x87: no min or max.
- SSE1: min/max for single precision scalars and vectors.
- SSE2: min/max for single and double precision scalars and vectors.
- AVX: as SSE2, but also supports the wider ymm vectors. (this is covered by the isTypeLegal check)

Few weeks ago, llvm completely inverted the debug info graph. Earlier each debug info node used to keep track of its compile unit, now compile unit keeps track of important nodes. One impact of this change is that the global variable's do not have any context, which should be checked before deciding to use AT_specification DIE.
