A lot of changes were suggested by Chris.

ExecveHandler.c:

* strlen() doesn't count NULL terminator in its size
* Use memcmp() instead of strcmp()
* Return result of the real execve(), not 0
* Search for path to bytecode file if not absolute/relative path

SysUtils.c:

lib/Support/CommandLine.cpp:
Many changes suggested by Chris. It's okay, I'll recover from the emotional
damage...maybe someday. :-)

Collapse ParseCStringVector into ParseStringVector.  Comment it.
Make it take a const input.
Use std::string::npos instead of -1 (what a mouthful!)
Make ParseEnvironmentOptions take const inputs.
Check its args at the very beginning.

Reorganize tests because we no longer cannonicalize X != 0 -> cast X to bool
In fact, we plan to eliminate cast to bool entirely.

For instructions in a delay slot of another instruction,
we no longer need to find the live-before set of the delayed
branch since that set is now included the live-before/after
set of the instructions in each delay slot.  Just assert that instead.

For an instruction with delay slots, mark all live values before

Give std::map<BasicBlock *, BasicBlock *> the short name BBMap, because
 it's used 7 different times.
Rename `getBackEdges' to `findAndInstrumentBackEdges', for clarity.
Remove some excess whitespace and commented-out code.
Use shorter forms of CallInst ctors.
Do not make `reopt_threshold' visible to the LLVM program, and do not
 pass it to the call to `reoptimizerInitialize'.  Don't pass the
 GlobalVariable representing it to any of our helper methods.
 `reopt_threshold' is an internal parameter of the reoptimizer, which
 InstLoops does not need to know about.
