632abdace8 * keep the syms that need to be checked for forward definitions in a 
separate list, so that procsyms, constsym, varsyms etc are not checked
    and so that every sym is checked only once (rather than at the end
    of every type block). This makes parsing units with lots of declarations
    much faster (e.g., compiling MacOSAll is now 2 to 3 times faster)

9955d5b061 o patch from Sergej Gorelkin to improvement code generation for string literals 
* Replaces linear search through assembler list by the hash lookup. 
    This considerably improves performance on large projects 
    (one example is winunits-jedi package, in which tcgstringconstnode.pass_generate_code 
     was top #1 in calltree, consuming about 12% IRefs).
  * Enables reusing memory locations for widestring constants 
    (and in general, the same approach may be used for any other type of constants).
  * Saves a sizeof(pointer) bytes per constant, by removing a location 
    which points to the string. This location is necessary for the 
    typed consts which may be modified, but redundant for string literals 
    because the language does not allow to modify string literals in any way.
