cf911de3c6 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).

bb6b121689 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.

fee76265ff 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.

trees.  But these tree nodes are now binary, not unary.

- Eliminate Sparc*Order classes, moving contents to Sparc*Class classes
   - get register name methods now return const char * const pointers instead

   - Added file header comments to SparcRegClassInfo.(cpp|h)
   - Moved BIG constant arrays out of SparcRegClassInfo.h, into
     SparcRegInfo.cpp.  This should allow a LOT of std::string constructors to
     not have to be called.

5f0eb8da62 - Cleaned up the interface to AnalysisUsage to take analysis class names 
instead of ::ID's.
 - Pass::getAnalysis<> now no longer takes an optional argument

1b51b1b4f9 Add function GetConstantValueAsUnsignedInt. 
Fix 2 bugs in FoldGetElemChain so index vector is not modified
when no GEPs are folded in, and so a hasLeadingZero is computed
only for the last folded GEP, not the one after that if any.

2e1749bbf8 * Move InstructionSelection Pass here instead of living in Sparc.cpp. It 
is platform independant afterall.
* Object orientize the functions, cleanup code a bit.  Instead of static
  global functions, the helpers for instruction selection are now part of
  the InstructionSelection Pass class.
