3104fa4a71 signficant cleanups to EmitGlobalConstant (including streamerization 
of int initializers), change some methods to be static functions,
use raw_ostream::write_hex instead of a smallstring dance with 
APValue::toStringUnsigned(S, 16).

377bd87849 Now that we have everything nicely factored (e.g. asmprinter is not 
doing global variable classification anymore) and hookized, sink almost
all target targets global variable emission code into AsmPrinter and out
of each target.

Some notes:

1. PIC16 does completely custom and crazy stuff, so it is not changed.
2. XCore has some custom handling for extra directives.  I'll look at it next.
3. This switches linux/ppc to use .globl instead of .global.  If .globl is
   actually wrong, let me know and I'll fix it.
4. This makes linux/ppc get a lot of random cases right which were obviously
   wrong before, it is probably now a bit healthier.
5. Blackfin will probably start getting .comm and other things that it didn't
   before.  If this is undesirable, it should explicitly opt out of these
   things by clearing the relevant fields of MCAsmInfo.

This leads to a nice diffstat:
 14 files changed, 127 insertions(+), 830 deletions(-)

f904832189 hoist handling of external globals and special globals up to common code. 
This makes a similar code dead in all the other targets, I'll clean it up
in a bit.

This also moves handling of lcomm up before acquisition of a section,
since lcomm never needs a section.

5678a9711b - Add a comment to the callback indicating that it's *extremely* not a good 
idea, but unfortunately necessary.
- Default to using 4-bytes for the LSDA pointer encoding to agree with the
  encoded value in the CIE.

6f360c3c91 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.

d78fcdd332 Retrying r91337: 
The CIE says that the LSDA point in the FDE section is an "sdata4". That's fine,
but we need it to actually be 4-bytes in the FDE for some platforms. Allow
individual platforms to decide for themselves.
