5144a0d1e6 * only start a new object file for typed const data if we are instructed
to start a new section (no smart linking in the middle of section data)

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

8afffdb176 * moved get_string_symofs() to a virtual class method of
ttai_typedconstbuilder so that it can be overridden by other platforms
  * override get_string_symofs() for LLVM and always return 0, as you can't
    have labels in the middle of a declaration on that platform

a284902813 * emit the current offset when flushing tasmsymbols in the
ttai_lowleveltypedconstbuilder
   o set the offset to 0 in the llvm constbuilder before calling
     the lowlevel one, because it incorporates this offset already
     via getelementptr instructions

e0c1c4d3bf + support for merging multiple tai_strings/tai_consts emitted as part of the
same string constant to be merged together into a single tai_string
    (required to efficiently represent string constants in llvm assembler
     --i.e., without splitting them into bytes--, while keeping the
     flexibility in the typed constant parser to mix individual elements
     and strings)

9f39188253 * moved the tai_*typedconst classes to aasmcnst to make use of def-related
helpers in a cleaner way (defutils would not belong in the uses clause of
    aasmtai)

02ad2e4879 + unit with a buider class for typed constant/initialised data elements at
the assembler level
   o initially for use during the typed constant parsing, but usable anywhere
     we generate initialised data in the compiler
