For PR411:
No functionality changes, just improve the code by a) providing better
function names, b) eliminating a call to get_suffix and c) tightening up
a function elimination test to reduce further checking.

For PR411:
Don't try to be smart about fixing intrinsic functions when they're read

produce a explicit result. However it produces an implicit result in
AL which would be copied to a temp. The root operator of the matching
pattern is a mul so the use would expect it to produce a result.

1. Identify bytecode modules that have upgraded intrinsics by setting a
   boolean flag if we read a function prototype that needs upgrading.
2. Don't upgrade the CallInst instruction until after its been inserted
   into the basic block, and only if we know that we have seen an
   upgraded intrinsic function.

Don't forget about casting the result of an upgraded call to an intrinsic
in the case where it needs to cast back to a signed type.

1. Documentation upgrade.
2. Have UpgradeInstrinicCall return an Instruction* instead of a CallInst*
   and return the needed CastInst* if the result of the upgraded call needs
   to be casted back to a signed type.
