Oliver Stannard 7e7d983a87 Refactor backend diagnostics for unsupported features ... Re-commit of r258951 after fixing layering violation. The BPF and WebAssembly backends had identical code for emitting errors for unsupported features, and AMDGPU had very similar code. This merges them all into one DiagnosticInfo subclass, that can be used by any backend. There should be minimal functional changes here, but some AMDGPU tests have been updated for the new format of errors (it used a slightly different format to BPF and WebAssembly). The AMDGPU error messages will now benefit from having precise source locations when debug info is available. llvm-svn: 259498		2016-02-02 13:52:43 +00:00
