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

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

2431b6e63b * i8086-msdos internal linker: use a different approach for finding the stack

a762532ae1 * changed the MemPos field in TObjSection and TExeSection from aword to qword: 
1) aword follows the ALU size of the CPU, not the address size
