3d519c7bab * Multiplications by 2^X are turned into shifts. This factors code out of the 
getelementptr code path for use by other code paths (like malloc and alloca).
* Optimize comparisons with zero
* Generate neg, not, inc, and dec instructions, when possible.

This gives some code size wins, which might translate into performance.  We'll
see tommorow in the nightly tester.

49bf38f650 Always say "the test program", part 2. 
Refer to the various "modules" of bugpoint as "debuggers", not
 "debugging modes" or "modules". I think this is more evocative of
 how they typically act, and it's shorter.
Add a note about how a linker bug can crash bugpoint early.

bdd4bcee15 Minor edits to Description section. 
Add Design Philosophy as a separate subsection.  Clarify its last sentence.
Give Automatic Mode Selection a uniquely-named anchor.
Always call the program the "test program", instead of the "initial program",
 the "LLVM program", the "test case", the "resultant module", etc.
Try to explain the assumptions a little more, instead of just describing the
 process.

27798b47fb Without this option, the -run-llc mode does not work with shared objects at 
all, making it pointless for use with the code generator debugger.  With it,
it works like a charm.

8328d8589b * Align comments into 80 columns 
* Stop using full pathnames (we don't know where the source could be)
* Use only relative distance to the source, so a user can download the code and
  generate their own copy of the doxygen documentation easily
* Since `docs' has moved one level up, all relative path names lost a `..'
