abc77742c8 Fix this code to use DIScope instead of DICompileUnit, as in r90181. 
Don't print "SrcLine"; just print the filename and line number, which
is obvious enough and more informative.

25905c8336 Support spill comments. 
Have the asm printer emit a comment if an instruction is a spill or
reload and have the spiller mark copies it introdues so the asm printer
can also annotate those.

c7cfc94bcc Print out an informative comment for KILL instructions. 
The KILL pseudo-instruction may survive to the asm printer pass, just like the IMPLICIT_DEF. Print the KILL as a comment instead of just leaving a blank line in the output.

With -asm-verbose=0, a blank line is printed, like IMPLICIT?DEF.

10d3dc569b Instead of printing unnecessary basic block labels as labels in 
verbose-asm mode, print comments instead. This eliminates a non-comment
difference between verbose-asm mode and non-verbose-asm mode.

Also, factor out the relevant code out of all the targets and into
target-independent code.

fdd8790718 strength reduce a ton of type equality tests to check the typeid (Through 
the new predicates I added) instead of going through a context and doing a
pointer comparison.  Besides being cheaper, this allows a smart compiler
to turn the if sequence into a switch.

b633d7a665 Add a new virtual EmitStartOfAsmFile method to the AsmPrinter and use this 
to emit target-specific things at the beginning of the asm output.  This
fixes a problem for PPC, where the text sections are not being kept together
as expected.  The base class doInitialization code calls DW->BeginModule()
which emits a bunch of DWARF section directives.  The PPC doInitialization
code then emits all the TEXT section directives, with the intention that they
will be kept together. But as I understand it, the Darwin assembler treats
the default TEXT section as a special case and moves it to the beginning of
the file, which means that all those DWARF sections are in the middle of
the text.  With this change, the EmitStartOfAsmFile hook is called before
the DWARF section directives are emitted, so that all the PPC text section
directives come out right at the beginning of the file.

11b2fc9ea4 Change MCAsmStreamer to take an MCInstPrinter instead of a 
full AsmPrinter, and change TargetRegistry to keep track
of registered MCInstPrinters.

llvm-mc is still linking in the entire
target foo to get the code emitter stuff, but this is an
important step in the right direction.

a602bebb61 devirtualize AsmPrinter::printBasicBlockLabel since it is never overridden. 
Move GetMBBSymbol up to AsmPrinter and make printBasicBlockLabel use it so that
we only have one place that decides what to name bb labels.  Hopefully various
clients of printBasicBlockLabel can start using GetMBBSymbol instead.
