6f36fa981a Write llvm-tblgen backends as functions instead of sub-classes. 
The TableGenBackend base class doesn't do much, and will be removed
completely soon.

Patch by Sean Silva!

55dc5c77a3 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

387c9dcdda 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.

are only rejected because they can't be encoded into a 32-bit unit, not because
they contain an unencodable feature.

a98aa6ad1e 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.

7c422ac216 Partially address a README by having functionattrs consider calls to 
memcpy, memset and other intrinsics that only access their arguments
to be readnone if the intrinsic's arguments all point to local memory.
This improves the testcase in the README to readonly, but it could in
theory be made readnone, however this would involve more sophisticated
analysis that looks through the memcpy.

09b1366f3f Fix the verifier to handle intrinsics with LLVMMatchType parameters, where 
the return type of the intrinsic is not overloaded, i.e., where the type
being matched is some other parameter.  The argument to LLVMMatchType is
an index into the list of overloaded types (ignoring the fixed types),
but VerifyIntrinsicPrototype is expecting its arguments for LLVMMatchType
parameters to be indices into the combined list of _all_ return values and
parameters, not just the overloaded ones.

This patch changes TableGen to keep track for each overloaded type of the
corresponding index into the list of return values and parameters.  It
then generates the values expected by VerifyIntrinsicPrototype.
