Remove unused AsmPrinter OptLevel argument, and propogate.

- This more or less amounts to a revert of r65379. I'm curious to know what
happened that caused this variable to become unused.

Add an "alignment" field to the MachineFunction object. It makes more sense to
...
have the alignment be calculated up front, and have the back-ends obey whatever
alignment is decided upon.
This allows for future work that would allow for precise no-op placement and the
like.

Provide InitializeAllTargets and InitializeNativeTarget functions in the
...
C bindings. Change all the backend "Initialize" functions to have C linkage.
Change the "llvm/Config/Targets.def" header to use C-style comments to avoid
compile warnings.
llvm-svn: 74026

Introduce new headers whose inclusion forces linking and
...
initialization of all targets (InitializeAllTargets.h) or assembler
printers (InitializeAllAsmPrinters.h). This is a step toward the
elimination of relinked object files, so that we can build normal
archives.

Change MachineInstrBuilder::addReg() to take a flag instead of a list of
...
booleans. This gives a better indication of what the "addReg()" is
doing. Remembering what all of those booleans mean isn't easy, especially if you
aren't spending all of your time in that code.
I took Jakob's suggestion and made it illegal to pass in "true" for the
flag. This should hopefully prevent any unintended misuse of this (by reverting
to the old way of using addReg()).
