Added a *very* initial cut at a lexicon for LLVM. I don't plan to write
this whole thing. Just use the pattern in the file to add entries as you
think of them. This will be really helpful for newbies to advanced compiler
optimization techniques such as myself.

Bytecode File Format Changes:
- File format version number bumped to 4
- Writer will now align nothing
- Reader now only expects alignment for version 3 or earlier

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@15875 91177308-0d34-0410-b5e6-96231b3b80d8

Documented the removal of alignment in version 4 bytecode files (version 3
was released with LLVM 1.3). Alignment of fields can add severe size to
certain kinds of functions (those with lots of long format instructions) so
we decided to do away with alignment altogether in this bc version.

Re-fix hiding the Frame Pointer from the register allocator in functions
that have a frame pointer.  This change fixes Burg.  In addition, make
the necessary changes to floating point code gen and constant loading after
Chris Lattner's fixes to the asm writer.  These changes fix MallocBench/gs
