6b0a19c0ab * fixed getting the address of a far proc on i8086 after the hlcgllvm branch merge

003b283e55 * fixed thlcgcpu.g_exception_reason_save_const always generating a 286+ push 
instruction on i8086, regardless of current cpu level

b745dcc64c * moved g_external_wrapper() to the hlcg, and also g_intf_wrapper() because 
for some platforms it depends on that routine

a637fbe596 * moved all g_exception_*() methods to hlcgobj and cleaned them up (no more 
hardcoded registers for the most part)
  + added extra g_exception_discard_reason() that can be called when we only
    want to get rid of the currently pushed exception reason, and don't have
    to load it (so it can do nothing on platforms that don't use push/pop)

1516661249 + new chlcgobj class reference variable that can be used to call thlcg* 
virtual methods even when hlcg doesn't contain a valid instance

feb840b47f * support reg=NR_NO in thlcgcpu.reference_reset_base on i8086. This fixes test 
webtbs/tw26162.pp in the i8086 far data memory models.

on i8086

313240b9e8 * use a better way (suggested by Jonas) to determine whether a procedure is from 
the same unit

70a7ecd0fa + use 'push cs + call near' (which is both shorter and faster), instead of far 
call, when calling a far proc in the same segment

d8d3706462 + override hlcg.a_call_name for i8086 and dispatch to the appropriate type of 
call (near or far), according to whether the procdef is near or far, instead
  of relying on the default for the memory model

40a6a9c820 + added i8086 specific implementation of thlcgcpu.a_load_loc_ref, which handles 
6-byte method pointers and other i8086 types that use loc.registerhi
* changed the i8086 specific code in tcgassignmentnode.pass_generate_code to
  use hlcg.a_load_loc_ref

2e7aab0155 * refactored i8086's thlcgcpu.location_force_mem: 
o The checks for types that need special handling moved to separate methods,
    because they'll probably be used by the other hlcg.a_load*loc* methods as
    well.
  o Use voidcodepointertype and voidpointertype to avoid the ifs for checking
    the memory model.

4e60d2316f * support implicit pointer types (classes, dynarrays, ansistrings, etc.) in 
i8086's thlcgcpu.getaddressregister and thlcgcpu.reference_reset_base

ce59c4616f * assume SS for the segment of references that have BP as base in

ead05754b4 + implemented hlcg.a_loadaddr_ref_reg for i8086, which uses tosize to determine whether the destination is a far pointer, instead of using the presence of ref.segment

26b53607f8 + added method reference_reset_base with support for different pointer types to 
the high level code generator. All hlcg code, except for the jvm code
  generator, updated to use the new method. I didn't update jvm (it still uses
  the method from cgutils), because I'm not familiar with that platform, so I
  might get the types wrong.

3cd9cef182 + added a far pointer aware implementation of hlcg.getaddressregister for i8086. 
This should allow writing memory model independent code in the FPC code
  generator.
