14d8c7a6a0 * Don't save LR when outputting globals: it's already saved on the stack once
for the function
* Registers aren't necessarily sequential wrt their enums, don't rely on it
  when emitting function arguments into sequential registers
* Remove X86-specific comments about AL/BL/AH/BH/EDX/etc
* Add an abort() for an unimplemented signed right shift
* The src operand for a GEP was never emitted!  Fixed.
* We can skip zero-valued GEP indices as they are no-ops.

"Hello, World!" now works.

0692dbfa10 Remove files no longer needed. ConstantReader and InstructionReader were
integrated into Reader. Parser.* was just a bad idea. AnalyzerInternals.h
is no longer needed. ReaderPrimitives.h was integrated into Reader.h and
Reader.cpp. Dumper.cpp was integrated into Analyzer.cpp. ReaderInternals.h
became Reader.h. AnalyzerWrappers.cpp was integerated into
ReaderWrappers.cpp

060d25d1dc MAJOR REWRITE.
- stop passing Buf/BufEnd to every function (now member vars)
- internalize things that used to be in a header file that no one else
  included/needed.
- Remove defunct BCR_TRACE lines
- Standardize error handling with the PARSE_ERROR macro.
- Integrate ConstantReader.cpp and InstructionReader.cpp and reorgnize
  the definition order so that gcc has a chance at optimizing this module
- Standardize case and style of method names.
- Eliminate unneeded header files
- Prepare for Type != Value (bug122) change by splitting Types into their
  own data structures.
- Implement the BytecodeHandler interface calls.
- Provide default implementation of BytecodeHandler interface.

1b17438aa8 The code generator should work with unreachable blocks. If not, then this
is a bug that should be fixed in the code generator, not papered over with
the simplifycfg pass.  Eliminating this makes bugpoint much more useful
