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.

 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.

Made the USE_SPEC option work.
Silenced unnecessary error output from the cmp command when checking for
updates to lex/yacc generated files.  This fixes a problem where we get error
messages the first time the file is generated.
Fixed the distclean option.  It is now in the Makefile (i.e. only runs in the
top level source directory), removes more files, and plays nicely with
external project Makefiles.
