b657c4cdc3 emit jump table an alias ".set" directives through MCStreamer as 
assignments.

.set x, a-b

is the same as:

x = a-b

ff234e09b9 Eliminate SetDirective, and replace it with HasSetDirective. 
Default HasSetDirective to true, since most targets have it.

The targets that claim to not have it probably do, or it is
spelled differently. These include Blackfin, Mips, Alpha, and
PIC16.  All of these except pic16 are normal ELF targets, so
they almost certainly have it.

3dd38a8112 eliminate MCAsmInfo::NeedsSet: we now just use .set on any platform 
that has it.

6f2d99df03 move "EOL" from asmprinter to dwarfprinter. It should eventually 
be completely eliminated, but today is not that day.

handle the comment better, MCize the non-.sleb case.

edf96a4cc3 add a new DwarfPrinter::EmitEncodingByte method which handles 
pretty printing encoding comments and eliminates redundancy on
the client side.  We now get pretty dwarf like this again:

        .byte   255                                         ## @LPStart Encoding = omit
        .byte   0                                           ## @TType Encoding = absptr
        .byte   0x28                                        ## @TType base offset
        .byte   3                                           ## Call site Encoding = udata4
        .byte   0x1a                                        ## Call site table size
...

69bb026835 rename the dwarf class to DwarfPrinter. This matches the filename 
and much more accurately describes what it is all about.

8b5d55ed06 now that MCSymbol::print doesn't use it's MAI argument, we can 
remove it and change all the code that prints MCSymbols to use 
<< instead, which is much simpler and cleaner.

9372f4d7d5 Simply LSDA lable emission to use a direct special-case output instead of 
EmitLabel()

20eac92d88 Clean up LSDA name generation and use for SJLJ exception handling. This 
makes an eggregious hack somewhat more palatable. Bringing the LSDA forward
and making it a GV available for reference would be even better, but is
beyond the scope of what I'm looking to solve at this point.

Objective C++ code could generate function names that broke the previous
scheme. This fixes that.

06fa176862 prune the #includes in raw_ostream.h by moving a 
member out of line. ftostr is not particularly speedy,
so that method is presumably not perf sensitive.

fbcc663cbf llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable. 
This adds location info for all llvm_unreachable calls (which is a macro now) in
!NDEBUG builds.
In NDEBUG builds location info and the message is off (it only prints
"UREACHABLE executed").

56d0659726 assert(0) -> LLVM_UNREACHABLE. 
Make llvm_unreachable take an optional string, thus moving the cerr<< out of
line.
LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for
NDEBUG builds.

47054f3d57 Split out the Dwarf writer stuff into separate files. This is a much more 
logical/sane approach to organizing all of the stuff that goes into writing out
DWARF information. Honestly? even this is too complex for what it's supposed to
be doing.

Trivia: It *looks* like there would be functionality changes, however there aren't!
