8e296cc9d9 Fix potentially N^2 behavior handling arrays with many of the 
same value which get RAUW'd.  This speeds up reading the .bc
file in PR1616 from 852s to 0.19s on my G5 with a debug build.

5da3149de5 When Intrinsic::getName is constructing names for overloaded intrinsics, 
use the ValueType name instead of the llvm type name, to match what the
verifier expects. For integers these are the same, but for floating-point
values the intrinsics use f32/f64 instead of float/double.

when a definition's visibility is different.  Likewise, the
visibility of two declarations mismatching is not an error.

d5f075ed16 Compute the argument list as lazily as possible. This ensures that clients 
that don't use it don't have to pay the memory cost for the arguments.  This
allows us to avoid creating Argument nodes for many prototypes and for clients
who lazily deserialize code from a bytecode file.
