3b9d6216a4 fix AsmPrinter::GetBlockAddressSymbol to always return a unique 
label instead of trying to form one based on the BB name (which
causes collisions if the name is empty).  This fixes PR6608

f08fde41f3 MC/Mach-O: Implement initial support for relaxation. 
- The implementation is currently very brain dead and inefficient, but I have a
   clear plan on how to fix it.

 - The good news is, it works and correctly assembles 403.gcc (when built with
   Clang, at '-Os', '-Os -g', and '-O3'). Even better, at '-Os' and '-Os -g',
   the resulting binary is exactly equivalent to that when built with the system
   assembler. So it probably works! :)

826cbac2a0 The check for coalescing a virtual register to a physical register, e.g. 
cl = EXTRACT_SUBREG reg1024, 1, is overly conservative. It should check
for overlaps of vr's live interval with the super registers of the
physical register (ECX in this case) and let JoinIntervals() handle checking
the coalescing feasibility against the physical register (cl in this case).
