b8883ea999 Reserve space for PHI nodes when we read them in. This provides a VERY
tasty 15% speedup on the testcase from Bill.

7467b5ff4e Use the version of getValue that takes the type plane instead of the type
if possible.  This provides a consistent 8.5% speedup.

8f99fbb02c 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.

4eb71c8940 Significantly clean up parsing of instructions. This exceptionizes and
simplifies the control flow a bit.  This provides a small (~3%) speedup,
but it's primarily a cleanup exercise.

55e1c2edfb 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.

f3d49adf85 - Finally nailed: test/Regression/Assembler/2002-08-16-ConstExprInlined.llx
- ParseConstantPool was resolving reference to value using the function
      slot # instead of the global slot #.
  - Bytecode reader changes:
    - Remove the failure<> template from Bytecode Reader
    - Remove extraneous #includes
    - s/method/function/ a bit
    - Eliminate the fwdRefs class that just added abstraction where it was not
      needed, making things more complex.
    - Use a vector instead of a list for function signatures.

have to support the cast instruction, so the function is renamed to getCast.
