7000bbb63f Fairly major overhaul of MachineInstr & Operand classes 
- Inline methods that are mostly a single line anyway
  - Eliminate several methods that were never called
  - Group methods a bit more consistently

dd74dc44b6 - Fix a really nasty bug in the bytecode reader that caused it to fail 
reading bytecode files with > 255 types in them, but only when optimization
    is enabled.  This was caused by GCC shrinking an enum to a single byte
    instead of a whole word.

dfc8fbf16b - Two minor improvements to the MachineInstr class to reduce footprint and

    bitvector.  Sped up LLC a little less than 10% in a debug build!

296c58a00c - Make sure to only keep track of mappings that the TD pass may need in the 
future.  This prevents having spurious map entries to nodes that we really
    don't care about.  This allows us to reenable the DeadNodeElim, which was
    disabled.

1276c50e7b As it turns out, we don't need a fully generic mapping copy ctor, we just need 
something that maps through a std::map.  Since this simplified the client and

2914391ab6 - Make DSCallSite not inherit from std::vector. Renamed methods slightly. 
Make copy ctor have two versions to avoid dealing with conditional template
    argument.  DSCallSite ctor now takes all arguments instead of taking one
    and being populated later.

c02c96c3de Added a first-class representation for each call site that can be 
used in the DS graphs.  Essentially, what was vector<DSNodeHandle>
before is now a DSCallSite with the same vector, plus pointers to the
CallInst and the caller Function.  The special-purpose class
BUDataStructure::CallSite is no longer needed.

3a54b695ce Significant improvement: GEP used by a load or store no longer generates 
a separate ADD; instead just use the indexed load/store instruction!
Also, a bug fix: folding a GEP with a leading non-zero index with
its predecessor was incorrect: now it only happens if the predecessor
is pointing to an indexable type (aka SequentialType).

b16f596ab4 Allow emission of names that start with an underscore. This is needed to 
interface with code that uses symbols in the ansi-c protected namespace.  In
most cases this comes from system header files, such as stdio.h.  In particular,
without this change, a reference to the __iob symbol is mangled into ll_iob,
which is not resolved by libc.

7436df838d Several major fixes, particularly in emitting constant aggregates: 
(1) Padding bytes between structure fields (for alignment) were never
    being emitted into the constant pool so the layout did not match!
(2) In printing constants, structures containing structures or arrays
    were never handled.
(3) Support new model for external/uninitialized/initialized globals.
    Uninitialized globals are no longer emitted since they are external.
    Initialized globals may go either in .bss or in .data.

Note that this does not fix bug:
FunctionResolve/2002-08-19-ResolveGlobalVars.ll because replaceAllUsesWith
breaks when a constantexpr is pointing to the thing being replaced.  This
is more of an infrastructure problem than anything.
