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.

fd85fdee7c Change how tblgen generates attributes for intrinsics to use a single 
switch.  With this newfound organization, teach tblgen how not to give
all intrinsics the 'nounwind' attribute.  Introduce a new intrinsic,
llvm.eh.resume, which does not have this attribute.  Documentation and uses
to follow.

4ef1119d94 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.

b5df29301c 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.

0e0d313fc0 Fix PR3994: LLVMMatchType arguments do not refer to absolute return value 
and argument positions but only to the overloaded intrinsic parameters.
Keep a separate list of these overloaded parameters in CodeGenTarget.cpp
so they can be resolved easily.  Remove assertions from IntrinsicEmitter.cpp:
they were harmless but confusing, and the assertions elsewhere in TableGen
will catch any incorrect values.

66f10b55ed New feature: add support for target intrinsics being defined in the 
target directories themselves.  This also means that VMCore no longer
needs to know about every target's list of intrinsics.  Future work
will include converting the PowerPC target to this interface as an
example implementation.
