e284f80948 inline away a form of IsPCRelative, eliminating the 
dead IsPCRel argument.

cff79125fb add some fixme's for MCizing. EH still has a few things that 
need to be MCized, but the last debug info thing are LEB and
cygwin specific (which the MC api doesn't support yet) and
one specific form of EmitReference which I'll tackle next.

d5d96f76d0 eliminate EOL, adding all comments with the OutStreamer.AddComment 
method.  With this, comments should end up on the same lines as the .byte
directives (for example) and we now get no output with:

$ llc CodeGen/X86/2009-02-12-DebugInfoVLA.ll -o - -filetype=null -asm-verbose

woot.

off "EOL".

d51f1bdc58 reapply r98035: 
Now that setStartLabel takes an MCSymbol, we can de-ID'ize
beginScope and RecordSourceLine.

43b812b6a8 add some extra checks. I'm not sure why, but this does unbreak a 
failure remaining on mainline.

f7ad2622cc change DbgScope to keep track of the start/end label as MCSymbol* 
now that the dependence on ID is removed from MMI.

a72a32a06b remove a useless optimization: now that label replacement never 
happens, the start/end of a scope can never be the same.

d4ce7a73e8 strength reduce MMI::MappedLabel to MMI::isLabelDeleted, 
and add a FIXME about how we are eventually going to zap this
lookup table once mc world domination is complete.

183e87502e now that the debug and eh emitters use a common .set counter, 
we can eliminate "flavor".

10d571f349 simplify EmitSectionOffset to always use .set if it is 
available, the only thing this affects is that we produce
.set in one case we didn't before, which shouldn't harm
anything.  Make EmitSectionOffset call EmitDifference
instead of duplicating it.
