5ef93e85b8 + added extra "orgsupreg" parameter to do_spill_read/do_spill_written/ 
do_spill_replace routines, will be necessary by llvm register
    allocator to determine the tdef corresponding to that register
  * replaced uses of taicpu with tai_cpu_abstract_sym in the register
    allocator so that it can work both with taicpu and taillvm instructions

5599870a4e * moved the register colouring and spill temp allocation to a virtual method, 
and made the related data structures protected instead of private, so they
    can be overridden

d13b510144 + helpers to convert tdefs to strings describing the types in llvm syntax. 
Other than arrays and complex procvardefs, all aggregates are currently
    handled as opaque arrays of bytes
   o special case: s80real (x87 extended type) is encoded as "array[0..9] of
     byte" inside arrays, because when using the llvm type describing
     "extended" llvm will handle it in an ABI-compliant way (allocating e.g.
     16 bytes for it on Darwin and x86-64 platforms). Loading/storing them
     always happens using instructions that only read/write 10 bytes, so
     we only have to take care to convert them to the actual extended type
     when indexing arrays/subscripting records (when records are no longer
     handled in an opaque way)

8ede313ba1 + llvm parameter manager: it reuses the native parameter manager to create 
the paraloc information, and then adds llvm-specific information to the
    paralocs
   o only partially implemented, in particular function result handling is
     not yet there

d245228ba6 + tcgllvm.a_label() and tcgllvm.a_jmp_always(). Special for llvm: every 
basic block must end with a terminator instruciton (such as a branch) ->
    when emitting a label, check whether the previous instruction is a
    terminator instruction and if not, add an unconditional branch to the
    label we are adding.
   o Implemented at the tcg instead of at the thlcgobj level because
    a) these methods don't need any high level type information
    b) implementing them in thlcgobj would require making thlcg.a_label()
       virtual and ensuring that no-one ever calls cg.a_label() in any
       generic code

1df3039424 + LLVM temp allocator based on new R_TEMPREGISTER register class. For every 
temp we allocate, we set the base register to a newly allocated
    R_TEMPREGISTER. This allows for uniquely identifying a temp even if its
    offset is modified.

c1cec52897 * fixed alignment of bitpacked arrays of ordinals/enums: the prevous code 
always returned the alignment of enum/ordinal by itself, which could be
    either bigger or smaller than what was required
  * for non-bitpacked regular arrays, always use the alignment of the elements
    instead of sometimes the natural alignment of the size of the elements
    (which can be different)

f348e89112 - removed too early assignment of have_first_symbol:=true, making the later
