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.

Add method for replacing instructions to LibCallSimplifier2012-11-11T03:51:43ZMeador Ingemeadori@codesourcery.com2012-11-11T03:51:43Zurn:sha1:b69bf6be1b042a5f06a623fc546107fc6d9f46c4
In some cases the library call simplifier may need to replace instructions
other than the library call being simplified. In those cases it may be
necessary for clients of the simplifier to override how the replacements
are actually done. As such, a new overrideable method for replacing
instructions was added to LibCallSimplifier.
A new subclass of LibCallSimplifier is also defined which overrides
the instruction replacement method. This is because the instruction
combiner defines its own replacement method which updates the worklist
when instructions are replaced.
