This moves the sema checking of the entrypoint sensitive HLSL attributes all into one place. This ended up being kind of large for a couple of reasons: - I had to move the call to CheckHLSLEntryPoint later in ActOnFunctionDeclarator so that we do this after redeclarations and have access to all of the attributes. - We need to transfer the target shader stage onto the specified entry point before doing the checking. - I removed "library" from the HLSLShader attribute value enum and just go through a string to convert from the triple - the other way was confusing and brittle.
