cc596225fa + thlcg.g_ptrtypecast_reg/ref() to typecast a pointer in a register, or the 
pointer type describing a reference, to another pointer type

76e0ee7a41 * fixed adding padding bytes before anonymous records: the alignment of such 
records is only known once we have completely parsed all of their data
    (the alignment of a record depends on the alignment requirements of its
     field with the largest alignment) -> only insert the padding bytes after
    completely parsing them

d2b55b6f07 * moved the recording of aggregate type information during typed constant 
parsing from nllvmtcon to aasmcnst
   o added automatic insertion of padding bytes when fields need to be aligned,
     so that once ncgvmt (and hopefully ncgrtti) are converted to the typed
     constant builder class, we can get rid of all the explicit alignment
     directives (only supported for non-bitpacked records for now)

b6fc2f1542 * don't emit the */pointer suffix for procdefs in llvmaddencodedtype_intern(), 
so that if a_loadaddr_ref_reg() is used to load the address of a procdef
    into a register, the getpointerdef(procdef) won't (wrongly) result in two
    *'s
   o the previous behaviour was necessary for the tck_simple_procvar2proc
     special case that was removed in the previous commit

cc4482d6f8 - removed tck_simple_procvar2proc, instead use 
procdef.getcopyas(procvardef,pc_address_only) as the def if we want to
    specify that we're interested in the address of a procedure/procvar of
    object

4acd43c643 * don't force simple function results in memory 
o results in simpler code, and more importantly is required for some code
     that expects a LOC_REGISTER after calling certain system unit helpers

50274f58b6 * ignore get/unget/alloc/dealloc of cpu registers when generating llvm code

     occasionally allocate them via the generic routines in case of e.g. a
     hardcoded use of a function return register

53e1d5c26f * fixed optimised form of a_cmp_const_reg_label(): when inverting the branch, we still 
have to emit the label we originally allocated for the fallthrough path (otherwise
    the branch is not inverted at all, and moreover the caller will also emit the
    original target label somewhere so it will be doubly defined)

c84a8a4bc2 * separate methods to get the size of the ansistring/unicode header and to 
get the offset relative from the returned label from
    emit_(ansi|unicode)_string() to the start of the string data
   o corrected return value for the offset on LLVM: it's always equal to the
     header size, since we can't emit labels in the middle of structured data
     there

7a10959aa0 + support for parsing structured data for which no tdef is available in 
advance (e.g. ansistring constants, as they consist of a header
    followed by an array of char equal to the string length, or RTTI data)
   o use begin_anonymous_record() to start recording the field types (if
     necessary for the current target), and end_anonymous_record() at the
     end to generate the recorddef
