213800d44b Clean up assembly statement separator support. 
The MC asm lexer wasn't honoring a non-default (anything but ';') statement
separator. Fix that, and generalize a bit to support multi-character
statement separators.

0514e10276 Speculatively revert commit 127478 (jsjodin) in an attempt to fix the 
llvm-gcc-i386-linux-selfhost and llvm-x86_64-linux-checks buildbots.
The original log entry:
Remove optimization emitting a reference insted of label difference, since
it can create more relocations. Removed isBaseAddressKnownZero method,
because it is no longer used.

917ca94111 Preliminary support for ARM frame save directives emission via MI flags. 
This is just very first approximation how the stuff should be done
(e.g. ARM-only for now). More to follow.

9c30c492df Restore r125595 (reverted in r126336) with modifications:

expression. If it is true, parse them like (). Enable this for ELF only.

cc474b4864 Model :upper16: and :lower16: as ARM specific MCTargetExpr. This is a step 
in the right direction. It eliminated some hacks and will unblock codegen
work. But it's far from being done. It doesn't reject illegal expressions,
e.g. (FOO - :lower16:BAR). It also doesn't work in Thumb2 mode at all.

like 6 is a fixed point of that and so the previous tests were OK :-)

3d9afa3c44 Don't relax org or align. They change size as the relaxation happens, but they 
are not actually relaxed. For example, a section with only alignments will never
needs relaxation.

e0e966982a Layout one section until no relaxations are done and then move to the next 
section.

This helps because in practice sections form a dag with debug sections pointing
to text sections. Finishing up the text sections first makes the debug section
relaxation trivial.

6979fc1057 MC/Mach-O: On second thought, use a custom hook for enabling aggressive 
IsSymbolRefDifferenceFullyResolved, it turns out this does change behavior on
enough cases for x86-32 that I would rather wait a bit on it.
 - In practice, we will want to change this eventually because it only means we
   generate less relocations (it also eliminates the need for the horrible
   '.set' hack that Darwin requires in some places).
