acd3ea8750 * m68k: Fixed parameter passing to conform to ABI: 
* records are passed by value
  * records with size of 1,2 or 4 are returned in registers
  * parameters with size<4 are justified on the stack according to big-endian target

Now everything except floating-point parameters is compatible with C code compiled with "-malign-int -mrtd".
Compatibility with "-mno-align-int" is achievable by changing target_info.maxCrecordalign to 2, but doings so causes a lot more troubles because RTL (incorrectly) assumes that records declared with {$PACKRECORDS C} are aligned to pointer size.

+ Reuse parameter locations. Since everything is passed on stack, it reduces code size quite a bit.
- tm68kparamanager.getintparaloc removed, generic implementation has been tested and works as expected.

dc17b55505 * switch to asmmode_i8086_intel instead of asmmode_i386_intel on i8086 when tp

7cfd7a66cd + create a special 'heap' segment with reserved space equal to heapsize (i.e. 
the value set by -Ch or the second parameter to the $M directive). This is
  equivalent to the heapmin value in Turbo Pascal 7 and ensures that the program
  has at least this amount of heap space available (otherwise DOS will show a
  'not enough memory' error and will refuse to load the program).

25037f5318 - MIPS: completely removed trgcpu.add_constraints method. 
While it can be correct from some point of view, it does not prevent aliasing a single-precision register into upper half of double-precision one. This is currently handled by making only even floating-point registers available to RA. At the same time, it somehow (possibly due to another bug in RA) generates a lot of unnecessary moves, as if physical double-precision registers conflict with each other. Anyway, removing it considerably improves the code without regressions in the test suite.

c260879439 * MIPS: updated registers, dropped special registers not recognized by GAS (actually, "pc" is recognized, but it is used only for MIPS16 mode, so it is easier to add back if/when this mode is supported), added FPU condition code registers ($fcc0..$fcc7). 
* cpubase.pas, std_regname: changed logic to lookup known names for special registers before resorting to default name, so that $fcc0..$fcc7 can be used as operands.

04d8e8a5dc * On 64-bit targets, handle abs(int64) internally, using the same code as for abs(longint), i.e. without branching. Both generic and x86-specific pass 2 code is already suitable for different operand sizes, only type checking needs removal of excessive conversions to 32 bits.
