4686f61002 * keep track of the temp position separately from the offset in references,
so that they can still be freed after the reference has been changed
    (e.g. in case of array indexing or record field accesses) (mantis #33628)

a25ebbba3e + added volatility information to all memory references
o separate information for reading and writing, because e.g. in a
     try-block, only the writes to local variables and parameters are
     volatile (they have to be committed immediately in case the next
     instruction causes an exception)
   o for now, only references to absolute memory addresses are marked
     as volatile
   o the volatily information is (should be) properly maintained throughout
     all code generators for all archictures with this patch
   o no optimizers or other compiler infrastructure uses the volatility
     information yet
   o this functionality is not (yet) exposed at the language level, it
     is only for internal code generator use right now

18a59dddb9 * use ctai_typedconstbuilder.get_dynstring_rec() to get the recorddef representing
string constants instead of giving an internal error if we can't find it in
    the current context (in most cases it will exist, but not when inlining a
    routine from another unit that accesses a locally declared string constant)

9a8a323578 * (again) fixed loading the address of the string data of an ansi/
unicodestring constants: specify the type of the pointer to the
    string record (which is indirect) rather than that of the string
    array (which will implicitly be the result of the getelementptr)

f402b0d7df * changed getpointerdef() into a tpointerdef.getreusable() class method
o allows removing the ugly x86 hacks

4c11d34169 * fixed loading the address of the string data of an ansi/unicodestring
constant in the llvm code generator (the constant is a record rather than
    a pointer to a record -> not indirect)

b176ed9f80 * ensure that the llvmst is initialised before using a field's llvmfieldnr
(and at the same time take advantage of this to perform a sanity check)

4f906fb9c9 * fixed datadef for untyped string constants (terminating #0 is one
character, not two)

than their type at the Pascal level

80c6225bf4 * fixed handling of comp and currency when they have to be handled by the
fpu: treat them as extended when they are loaded into registers, and as
    int64 when loading from/storing to memory

d04e05ff82 + handling of floating point constants in llvm code (just load them in a
register, llvm will take care of putting them in memory if necessary)
