bd0fa4c00d 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.

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.

d305e707a6 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.

83ec4b6711 Wrap MVT::ValueType in a struct to get type safety
and better control the abstraction.  Rename the type
to MVT.  To update out-of-tree patches, the main
thing to do is to rename MVT::ValueType to MVT, and
rewrite expressions like MVT::getSizeInBits(VT) in
the form VT.getSizeInBits().  Use VT.getSimpleVT()
to extract a MVT::SimpleValueType for use in switch
statements (you will get an assert failure if VT is
an extended value type - these shouldn't exist after
type legalization).
This results in a small speedup of codegen and no
new testsuite failures (x86-64 linux).
