e4feacf29d Load global variables and typed constants from different units using indirect references if necessary. 
ncgld.pas, tcgloadnode:
  + new method use_indirect_symbol to determine whether using an indirect reference is necessary at all
  * generate_threadvar_access & pass_generate_code: pass result of use_indirect_code() to RefAsmSymbol() for using an indirect access if needed

0c4edd2aa9 * fixed getting address of interface methods after r32414: interfaces are not 
a pointer to a vmt, but a pointer to a pointer to vmt (mantis #29086)
   o also adjusted the llvm type for interfaces accordingly

eaeb9d8351 * renamed thlcgobj.g_set_addr_nonbitpacked_record_field_ref() to 
thlcgobj.g_set_addr_nonbitpacked_field_ref() and adjusted it so that
    it also works for objects/classes (if the incoming reference points
    to the start of the class contents)
   o factored out the related code from tllvmsubscriptnode

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).

441e6c6083 Fix for Mantis #26177. Use the correct value for the method data when using a method pointer of a type or record helper. 
Please note that Delphi has the exact same bug as we have and thus code working in FPC will not work in Delphi.
Additionally taking the method address of a local variable or a local/global constant for a method pointer is dangerous as the variable (in case of constants is a temporary local variable) will go out of scope once the containing procedure/function/method exits!

ncgld.pas, tcgloadnode.pass_generate_code:
  * only use the value of Self if it is an implicit pointer object (class instance) or a class reference, but not for everything else (objects, records, primitive types)

+added test

d43d7e59b5 * partially converted the threadvar handling in tcgloadnode.pass_generate_code 
to use the hlcg in order to support the i8086 far data memory models. Only the
  instructions that handle the case when there's no thread manager installed
  (FPC_THREADVAR_RELOCATE=nil) are converted, since that's what's used on the
  msdos target. The rest still uses the low level code generator.
