two changes: 1) nuke ConstDataCoalSection, which is dead. 2) revise my previous patch for rdar://8018335, which was completely wrong. Specifically, it doesn't make sense to mark __TEXT,__const_coal as PURE_INSTRUCTIONS, because it is for readonly data. templates (it turns out) go to const_coal_nt. The real fix for rdar://8018335 was to give ConstTextCoalSection a section kind of ReadOnly instead of Text. llvm-svn: 112496

Make the big switch: Change MCSectionMachO to represent a section *semantically* instead of syntactically as a string. This means that it keeps track of the segment, section, flags, etc directly and asmprints them in the right format. This also includes parsing and validation support for llvm-mc and "attribute(section)", so we should now start getting errors about invalid section attributes from the compiler instead of the assembler on darwin. Still todo: 1) Uniquing of darwin mcsections 2) Move all the Darwin stuff out to MCSectionMachO.[cpp|h] 3) there are a few FIXMEs, for example what is the syntax to get the S_GB_ZEROFILL segment type? llvm-svn: 78547
