[llvm] r199575 - Move ARM build attributes into Support

Author: compnerd
Date: Sun Jan 19 02:25:27 2014
New Revision: 199575
URL: http://llvm.org/viewvc/llvm-project?rev=199575&view=rev
Log:
Move ARM build attributes into Support
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.
