/* Create a new temporary variable in the current m/u code block.
   The variable will be available (in scope)
   throughout the current code block, but not outside of it.

   `tag' is an arbitrary C identifier fragment
   that will be embedded in the temporary variable name:
   its purpose is purely to make the generated code
   a little more understandable by humans
   by giving some indication of what the variable is to be used for.
   These tags don't have to be unique in any respect:
   uniqueness of variable names is assured through other means.

   `type' is the C type to give the temporary variable.

   `sc' is the storage class for the variable -
   e.g. CAST_SC_NONE for a normal local variable,
   or CAST_SC_STATIC for a static variable.
