20d2d3e67f Re-did some of the text wrapping (sorry).
Made the "Getting Started Quickly" material its own section.  I think this makes
the document easier to read.
Added bars after every major section heading (to distinguish them more easily from
sub-section headings).
Renamed C front end to GCC front end, as we now support C and C++.
Updated material to reflect the new autoconf-style object root.
Added material about the llvm/runtime directory and the fact that you need to
install the GCC front end before building LLVM (before, it was optional).

39cacceb55 Ok, the "fix" for this is to do a real associative container. Symbol tables
are ordered by name, not by slot, so the previous solution wasn't any good.
On a large testcase, this reduces time to parse from 2.17s to 1.58s.

927b185c17 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.

8eb10cef39 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.

4ee8ef2a5d 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.

7d275f459b Avoid building data structures we don't really need. This improves the runtime
of a test that Bill Wendling sent me from 228.5s to 105s.  Obviously there is
more improvement to be had, but this is a nice speedup which should be "felt"
by many programs.

73ff5120eb Change MRegisterDesc::AliasSet, TargetInstrDescriptor::ImplicitDefs
and TargetInstrDescriptor::ImplicitUses to always point to a null
terminated array and never be null. So there is no need to check for
pointer validity when iterating over those sets. Code that looked
like:

if (const unsigned* AS = TID.ImplicitDefs) {
  for (int i = 0; AS[i]; ++i) {
    // use AS[i]
  }
}

was changed to:

for (const unsigned* AS = TID.ImplicitDefs; *AS; ++AS) {
  // use *AS
}
