Fix PR4748: don't fold gep(bitcast(x)) into bitcast(gep) when x
...
is itself a bitcast. Since we have gep(bitcast(bitcast(y))) in this
case, just wait for the two bitcasts to get zapped. This prevents
instcombine from confusing some aliasing stuff, and allows it to
directly eliminate the load in the testcase.

EraseInstFromFunction only add operands to the worklist if

to modify fcmp/icmp in place instead of creating a new one
and deleting the old one just to change the predicate.

identity, including the SubclassOptionalData flags. Also, fix the
Instruction::clone implementations to preserve the SubclassOptionalData
flags. Finally, teach several optimizations how to handle

This fixes the counterintuitive behavior of isIdenticalTo not comparing
the full value, and clone not returning an identical clone, as well as
some subtle bugs that could be caused by these.

More ProfileInfo improvements.
...
- Part of optimal static profiling patch sequence by Andreas Neustifter.
- Store edge, block, and function information separately for each functions
(instead of in one giant map).
- Return frequencies as double instead of int, and use a sentinel value for
missing information.

Switch obvious clients to Twine instead of utostr (when they were already using
...
a Twine, e.g., for names).
- I am a little ambivalent about this; we don't want the string conversion of
utostr, but using overload '+' mixed with string and integer arguments is
sketchy. On the other hand, this particular usage is something of an idiom.

More migration to raw_ostream, the water has dried up around the iostream hole.

- Some clients which used DOUT have moved to DEBUG. We are deprecating the
"magic" DOUT behavior which avoided calling printing functions when the
statement was disabled. In addition to being unnecessary magic, it had the
downside of leaving code in -Asserts builds, and of hiding potentially
unnecessary computations.
