7b093a1c2f Extend 'readonly' and 'readnone' to work on function arguments as well as 
functions. Make the function attributes pass add it to known library functions
and when it can deduce it.

ba6c1893c9 Use the AttributeSet instead of AttributeWithIndex. 
In the future, AttributeWithIndex won't be used anymore. Besides, it exposes the
internals of the AttributeSet to outside users, which isn't goodness.

a16e5519db Change 'AttrVal' to 'AttrKind' to better reflect that it's a kind of attribute instead of the value of the attribute.

62a846033f Make the AttrListPtr object a part of the LLVMContext. 
When code deletes the context, the AttributeImpls that the AttrListPtr points to
are now invalid. Therefore, instead of keeping a separate managed static for the
AttrListPtrs that's reference counted, move it into the LLVMContext and delete
it when deleting the AttributeImpls.

839f6c1a88 Remove exception handling usage from tblgen. 
Most places can use PrintFatalError as the unwinding mechanism was not
used for anything other than printing the error. The single exception
was CodeGenDAGPatterns.cpp, where intermediate errors during type
resolution were ignored to simplify incremental platform development.
This use is replaced by an error flag in TreePattern and bailout earlier
in various places if it is set.

a77399599d Attributes Rewrite 
Convert the internal representation of the Attributes class into a pointer to an
opaque object that's uniqued by and stored in the LLVMContext object. The
Attributes class then becomes a thin wrapper around this opaque
object. Eventually, the internal representation will be expanded to include
attributes that represent code generation options, etc.

2e87ef0470 Write llvm-tblgen backends as functions instead of sub-classes. 
The TableGenBackend base class doesn't do much, and will be removed
completely soon.

b787e2914f Reimplement the intrinsic verifier to use the same table as Intrinsic::getDefinition, 
making it stronger and more sane.

Delete the code from tblgen that produced the old code.

Besides being a path forward in intrinsic sanity, this also eliminates a bunch of
machine generated code that was compiled into Function.o

3d3d2be19b enhance the intrinsic info stuff to emit encodings that don't fit in 32-bits into a 
separate side table, using the handy SequenceToOffsetTable class.  This encodes all
these weird things into another 256 bytes, allowing all intrinsics to be encoded this way.

288872000a finish encoding all of the interesting details of intrinsics. Now intrinsics 
are only rejected because they can't be encoded into a 32-bit unit, not because
they contain an unencodable feature.

294ca0bfbc Significantly reduce the compiled size of Functions.cpp by turning a big blob of tblgen 
generated code (for Intrinsic::getType) into a table.  This handles common cases right now,
but I plan to extend it to handle all cases and merge in type verification logic as well
in follow-on patches.

all intrinsics the 'nounwind' attribute.  Introduce a new intrinsic,
llvm.eh.resume, which does not have this attribute.  Documentation and uses
