7e6b286041 Initial checkin of profiling instrumentation pass. So far, despite the 
file name, we only support function profiling.  This will be fixed in the
near future.

do something dumb, and inefficient, but more complete.

PHI node entries for unwind instructions just like for call instructions which
became invokes!  This fixes PR57, tested by

51684bea99 Make this pass substantially stronger by having it delete dead return values 
as well as arguments.  Now it can delete arguments and return values which are
only passed into other arguments or are returned, if they are dead.  This causes
it to delete several hundred extra args/retvals from the C++ hello world program,
shrinking it by about 2K.

a567862e89 Do not move variable sized allocations to the top of the caller, which might 
break dominance relationships, and is otherwise bad.  This fixes bug:
Inline/2003-10-13-AllocaDominanceProblem.ll.  This also fixes miscompilation
of 3 176.gcc source files (reload1.c, global.c, flow.c)

af8f585013 Checkin an improvement contributed by Bill: 
Only transform call sites in a setjmp'ing function which are reachable from
the setjmp.  If the call dominates the setjmp (for example), the called
function cannot longjmp to the setjmp.

This dramatically reduces the number of invoke instructions created in some
large testcases.

7519b1216b Add support to the loop canonicalization pass to make it transform loops to 
have a SINGLE backedge.  This is useful to, for example, the -indvars pass.

This implements testcase LoopSimplify/single-backedge.ll and closes PR#34

510dfc942a The preheader insertion pass only depends on the CFG. Mark it as such, which 
allows GCCAS to only run it once.
