c83a0bb4b6 Make changes in instruction and pattern definitions so that tablegen does not 
complain it cannot infer types in patterns. Fix a mistake in definition of 
SDT_MipsExtractElementF64.

a608b612f1 Add support for GR32 <-> FR32 cross class copies. 
We already support GR64 <-> VR128 copies.  All of these copies break
partial register dependencies by zeroing the high part of the target
register.

d3151e11e8 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.

dedb558e4d Constrain register classes instead of emitting copies. 
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.

1d3105c3d3 Add a MinNumRegs argument to MRI::constrainRegClass(). 
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.

f623ea5484 Converted Exception demo over to using new 3.0 landingpad instruction. This 
was compiled and tested on OS X 10.7.1. It was not tested on LINUX. In 
addition the defined OLD_EXC_SYSTEM was not tested with this version.

cce0f439c0 This is a hack to get the demo working with the new 3.0 exception 
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.

978ef840ac The SSE version differences for fmin/fmax are more involved than I thought. 
- 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)

5d43ab8434 Do not unnecessarily use AT_specification DIE because it does not add any value. 
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.
