Ok, the "fix" for this is to do a real associative container. Symbol tables

Major refactoring of the bytecode reader. This includes the following
...
changes:
* BytecodeReader::getType(...) used to return a null pointer
on error. This was only checked about half the time. Now we convert
it to throw an exception, and delete the half that checked for error.
This was checked in before, but psmith crashed and lost the change :(
* insertValue no longer returns -1 on error, so callers don't need to
check for it.
* Substantial rewrite of InstructionReader.cpp, to use more efficient,
simpler, data structures. This provides another 5% speedup. This also
makes the code much easier to read and understand.

Eliminate the old LateResolveValues data structure, replacing it with a
...
new, simpler, ForwardReferences data structure. This is just the first
simple replacement, subsequent changes will improve the code more.
This simple change improves the performance of loading a file from HDF5
(contributed by Bill) from 2.36s to 1.93s, a 22% improvement. This
presumably has to do with the fact that we only create ONE placeholder for
a particular forward referenced values, and also may be because the data
structure is much simpler.

This patch substantially simplifies and cleans up handling of basic blocks
...
in the bytecode parser. Before we tried to shoehorn basic blocks into the
"getValue" code path with other types of values. For a variety of reasons
this was a bad idea, so this patch separates it out into its own data structure.
This simplifies the code, makes it fit in 80 columns, and is also much faster.
In a testcase provided by Bill, which has lots of PHI nodes, this patch speeds
up bytecode parsing from taking 6.9s to taking 2.32s. More speedups to
follow later.
