Emit .cfi_sections before the first .cfi_startproc GNU as rejects input where .cfi_sections is used after .cfi_startproc, if the new section differs from the old. Adjust our output to always emit .cfi_sections before the first .cfi_startproc to minimize necessary code. Differential Revision: https://reviews.llvm.org/D28011 llvm-svn: 290817

Canonicalize the representation of empty an expression in DIGlobalVariableExpression This change simplifies code that has to deal with DIGlobalVariableExpression and mirrors how we treat DIExpressions in debug info intrinsics. Before this change there were two ways of representing empty expressions on globals, a nullptr and an empty !DIExpression(). If someone needs to upgrade out-of-tree testcases: perl -pi -e 's/(!DIGlobalVariableExpression\(var: ![0-9]*)\)/\1, expr: !DIExpression())/g' <MYTEST.ll> will catch 95%. llvm-svn: 312144
