glsl: fix use-after free bug/crash in ast_declarator_list::hir()
The call to get_variable_being_redeclared() may delete 'var' so we can't reference var->name afterward. We fix that by examining the var's name before making that call. Fixes valgrind warnings and possible crash when running the piglit tests/spec/glsl-1.30/execution/clipping/vs-clip-distance-in-param.shader_test test (and probably others).
