Make necessary changes to support DIV -> [SUF]Div. This changes llvm to
have three division instructions: signed, unsigned, floating point. The
bytecode and assembler are bacwards compatible, however.

with ParseBytecodeFile used to leak both a ModuleProvider (and related
bytecode parser stuff attached to it) AND a file descriptor, which was
never closed. This prevented gccld/llvm-ld/llvm-link from linking together
apps with more that ~252 .bc files on darwin.

Final commit for this bug. This removes the last EH holdouts in LLVM
and turns off exception support by using the -fno-exceptions option. This
leads to the following reduction in library and executable sizes:

Make the Bytecode Reader use setjmp/longjump instead of exceptions to handle
errors. The alternative was even uglier than setjmp/longjump as it would
impact the interface and workings of nearly every function in the reader.

bytecode reading. This code is crufty, the result of much hacking to get things
working correctly. Cleanup patches will follow.

lookups instead of linear time lookups. This speeds up bc parsing of a

Remove the "processFunctions" boolean from ParseBytecode as it is no
longer needed. This is part of avoiding double reading of functions
when analyzing bytecode.

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

- encode/decode target triple and dependent libraries
bug 401:
- fix encoding/decoding of FP values to be little-endian only
bug 402:
- initial (compatible) cut at 24-bit types instead of 32-bit
- reduce size of block headers by 50%
Other:
- cleanup Writer by consolidating to one compilation unit, rem. other files
- use a std::vector instead of std::deque so the buffer can be allocated
in multiples of 64KByte chunks rather than in multiples of some smaller
(default) number.

- Add read_float and read_double in preparation for a correct
implementation of bytecode floating point support.

- get rid of PARSE_ERROR macro
- add error(std::string) function
- use error(std::string) for all errors
- make input dependent asserts call error(std::string) instead
- ensure asserts are only for logic bugs, not input discrepancies.

too soon so the function data was not getting dumped (it was generated
after the call handleFinish). Also cleaned up the output format for
proper indentation.

mistaken for anything else.
- Move function descriptions to Reader.cpp file per Chris.
- Remove tabs.
