This moves the ARM build attributes definitions and support routines into the Support library. The support routines simply permit the conversion of the value to and from a string representation. The movement is prompted in order to permit access to the constants and string representations from readobj in order to facilitate decoding of the attributes section. llvm-svn: 199575
