44232deeda ConstantPointerRef's are no longer emitted. This saves 20028 bytes in the
bytecode files when compiling 176.gcc, but more importantly will make it

of forcing them to go through ConstantPointerRef's.  This allows bytecode

ed98fd7216 Change all of the bytecode reader primitives to throw exceptions instead of
returning error codes.  Because they don't return an error code, they can
return the value read, which simplifies the code and makes the reader more
efficient (yaay!).

Also eliminate the special case code for little endian machines.

106bba1e9b The new bytecode format supports emitting strings a special case. This is
intended to save size (and does on small programs), but on big programs it
actually increases the size of the program slightly.  The deal is that many
functions end up using the characters that the string contained, and the
characters are no longer in the global constant table, so they have to be
emitted in function specific constant pools.

This pessimization will be fixed in subsequent patches.

accd21042c Do not bother to emit a BytecodeBlock for an empty symbol table. This commonly
occurs when the symbol table for a module has been stripped, making all of the
function local symbols go away.

This saves 6728 bytes in the stripped bytecode file of 254.gap (which obviously
has 841 functions), which isn't a ton, but helps and was easy.

80daeb4cdb Fix PR#193.
Modified ReadArchiveBuffer() so that it dynamically allocates the
std::string object used to hold the bytecode object file's name.  This is
necessary because it is passed by reference to the new Module that is
allocated to represent the bytecode object, and previously we were
using a std::string that disappeared on function exit.

e962a55ac5 In getObjectType(), doxygenify comment, and take a pointer to the
beginning of the archive member data as an argument.

Get rid of ParseLongFilenameSection(), which is dead.

In ReadArchiveBuffer(), implement support for 4.4BSD/MacOSX long filenames.
This is kind of invasive, because they prepend the long filename to the archive
member data, and then lie about the size. So we have to keep track of the real
size.

a2ac517a20 Emit & read more compressed bytecode by not emitting a bytecodeblock for
each basic block in function.  Instead, just emit a stream of instructions,
chopping up basic blocks based on when we find terminator instructions.  This
saves a fairly substantial chunk of bytecode space.  In stripped, sample
cases, for example, we get this reduction in size:

197.parser: 163036 -> 137180:  18.8% reduction
254.gap   : 844936 -> 689392:  22.6%
255.vortex: 621724 -> 528444:  17.7%

...

Not bad for something this simple.  :)  Note that this doesn't require a new
bytecode version number at all, though version 1.1 should not need to support
the old format.

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.

6f7b5bd63f 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.

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.
