f8fbdb5ded Do not cannonicalize (X != 0) into (cast X to bool)

93e4916c37 Reorganize tests because we no longer cannonicalize X != 0 -> cast X to bool 
In fact, we plan to eliminate cast to bool entirely.

5c9ccccd96 Change cannonicalization rules: add X,X is represented as multiplies, multiplies 
of a power of two are represented as a shift.

1e41dd39ae Make MInst2LVSetBI and MInst2LVSetAI be hash_maps instead of maps. 
Add some comments and non-const methods to fix constness problems.

3862c570bc 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.

llvm-svn: 7796

e456b5fc93 For an instruction with delay slots, mark all live values before 
the instruction as being live before/after the delay slot
instructions as well.

9aa6b2db94 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.

b84423a6e8 Merged in changes between PRE11_ROOT and LLVM_PRE111 (i.e. the beginning of 
the pre-release 1.1 branch and pre-release 1.1.1).
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.

84e5185cbd Add a new -enable-cygwin-compatible-output argument, which make the output more 
consumably by the cygwin assembler.  This is really just a nasty hack until we
