simplify DarwinTargetAsmInfo::SelectSectionForGlobal a bit and make it more aggressive, we now put: const int G2 __attribute__((weak)) = 42; into the text (readonly) segment like gcc, previously we put it into the data (readwrite) segment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77104 91177308-0d34-0410-b5e6-96231b3b80d8

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? git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78547 91177308-0d34-0410-b5e6-96231b3b80d8
