abf6412c09 This patch substantially simplifies and cleans up handling of basic blocks 
in the bytecode parser.  Before we tried to shoehorn basic blocks into the
"getValue" code path with other types of values.  For a variety of reasons
this was a bad idea, so this patch separates it out into its own data structure.

This simplifies the code, makes it fit in 80 columns, and is also much faster.
In a testcase provided by Bill, which has lots of PHI nodes, this patch speeds
up bytecode parsing from taking 6.9s to taking 2.32s.  More speedups to
follow later.

Bill gave me from 8.69s to 6.90s.

82f64531f6 All of our supported operating systems (so far) and FreeBSD technically 
want you to include <sys/stat.h> for fstat(), struct stat, and friends.

cc593fb6c6 Rename AbstractModuleProvider -> ModuleProvider, to match the header file name, 
and because, while the class used by the interface is abstract, the actual
concept is not.

c7caffab32 There is no need for BytecodeParser to be an AbstractTypeUser. Instead, it 
can just use PATypeHolders

1e9402d93d Define the instance variable Buffer, not the automatic variable Buffer. 
This was causing us to munmap random stuff, which is obviously bad.

89f4dcf5bc Added code that ensures that we pass the beginning of the data buffer to 
the parsing routines regardless of whether the buffer is re-aligned or not.

0c0a882bc3 Suggestions made by Chris: 
* Instead of a #define, use inline function
* Fix the name on the #define, errr... now inline function to be more logical:
  it doesn't CHECK the alignment, it PERFORMS the alignment
* To get string name of a Type*, use getDescription(), not getName()

6e9a3517f2 * Cleaned up code: 
- no more passing around a string pointer to set errors
  - no more returning booleans and checking for errors, we use C++ exceptions
* Broke functionality into 2 new classes, one reads from file, one from a stream
* Implemented lazy function streaming - the parser can read in a function at-a-time
