MC/Mach-O: For PCrel relocations, we need to compensate for the PCrel adjustment when determining if we need a scattered relocation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98082 91177308-0d34-0410-b5e6-96231b3b80d8

MC tweak symbol difference resolution for non-local symbols. When the non-local symbol in the expression is in the same fragment as the second symbol, the assembler can still evaluate the expression without needing a relocation. For example, on ARM: _foo: ldr lr, (_foo - 4) rdar://10348687 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148341 91177308-0d34-0410-b5e6-96231b3b80d8

Darwin assembler improved relocs when w/o subsections_via_symbols. When the file isn't being built with subsections-via-symbols, symbol differences involving non-local symbols can be resolved more aggressively. Needed for gas compatibility. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146054 91177308-0d34-0410-b5e6-96231b3b80d8
