3a29d2d327 For now disable MDNode uniquing. This fixes llvm-gcc bootstrap failure on certain Mac OS X 10.5. I am working on a proper fix.

2cd5155c0e Free the constants that have no uses in ~LLVMContext. 
This fixes leaks from LLVMContext in multithreaded apps.
Since constants are only deleted if they have no uses, it is safe to not delete
a Module on shutdown, as many single-threaded tools do.
Multithreaded apps should however delete the Module before destroying the
Context to ensure that there are no leaks (assuming they use a different context
for each thread).

de86d473fc Add an 'inline hint' attribute to represent source 
code hints that it would be a good idea to inline
a function ("inline" keyword).  No functional change
yet; FEs do not emit this and inliner does not use it.

58cfa3b137 Rename Instruction::isIdenticalTo to Instruction::isIdenticalToWhenDefined, 
and introduce a new Instruction::isIdenticalTo which tests for full
identity, including the SubclassOptionalData flags. Also, fix the
Instruction::clone implementations to preserve the SubclassOptionalData
flags. Finally, teach several optimizations how to handle
SubclassOptionalData correctly, given these changes.

This fixes the counterintuitive behavior of isIdenticalTo not comparing
the full value, and clone not returning an identical clone, as well as
some subtle bugs that could be caused by these.

Thanks to Nick Lewycky for reporting this, and for an initial patch!

63a03cf585 Allocate the basic types inside the LLVMContextImpl instance, 
rather than separately with new. Move the members above the
TypeMap members to avoid destruction order issues. This fixes
a leak of these objects, and eliminates an extra level of
indirection in Type::getInt32Ty and friends.

2a610c7387 Update DebugInfo interface to use metadata, instead of special named llvm.dbg.... global variables, to encode debugging information in llvm IR. This is mostly a mechanical change that tests metadata support very well. 
This change speeds up llvm-gcc by more then 6% at "-O0 -g" (measured by compiling InstructionCombining.cpp!)
