Add -f[no-]double-square-bracket-attributes as new driver options to control use of [[]] attributes in all language modes. This is the initial implementation of WG14 N2165, which is a proposal to add [[]] attributes to C2x, but also allows you to enable these attributes in C++98, or disable them in C++11 or later. llvm-svn: 315856

Compound literals, enums, et al require const expr Summary: Compound literals, enums, file-scoped arrays, etc. require their initializers and size specifiers to be constant. Wrap the initializer expressions in a ConstantExpr so that we can easily check for this later on.
