0fc1fd6ac1 * replaced current_procinfo.currtrue/falselabel with storing the true/false 
labels of LOC_JUMP in the node's location. This generates some extra jumps
    for short circuit boolean and/or-expressions if optimizations are off, but
    with optimisations enabled the generated code is the same (except for JVM
    because the jump threading optimisation isn't enabled there yet).

8977c0fc78 * TExeSection.Size and .DataPos changed from aword to qword, because: 
1) aword follows the ALU size of the CPU, not the address type

Jonas Maebe
be9d2b1c26 * implement concatcopy for complex types by calling the llvm.memcpy() 
intrinsic. This may insert actual calls to a function called memcpy with
    the signature of the libc function, but llvm optimizers are free to
    insert such calls by themselves already. This means that for non-libc
    targets, we will have to add weak symbols for memcpy/memmove/memset
    that call through to move/fillchar when using LLVM, so that these
    implementation are used when not linking to libc

bfa94ae908 * further (final?) reworking of llvm external symbol handling: 
o all external symbol definitions are now inserted in the llvmtype post pass
     based on all declarations and types used in llvm instructions

d7f6744f7b * converted ncgrtti to the high level typed constant builder 
o the result is still not very clean due to the fact that this data
     is almost completely unstructured due to variable-length strings
     everywhere, which means that
    a) we cannot just load recorddefs from the system or typeinfo unit
       and use those as templates
    b) we cannot easily reuse the recorddefs we create ourselves (except
       if the strings have the same length -- this is the reason for all
       of the names specified to begin_anonymous_record: to reuse defs
       as much as possible rather than creating new ones all the time)
    c) we have to add explicitly aligned subrecords everywhere to insert
       explicit alignment on platforms that need it
