346adf7f55 * replace explicit (sometimes incomplete) tests with calls to doshortbooleval() 
* the c-style boolean evaluation of "and" is independent of short-circuit evaluation
    (you always have to consider the complete values in case the first one is <> 0)

4964f5cf76 * Count the number of interferences with real registers. 
* Do not coalesce registers 'u' and 'v' if 'u' is the last usable real register available for imaginary register 'n' which also interferences with 'v'.
    This prevents endless spilling in some cases for constrained CPUs such as AVR. Resolves issue #37421.
    Also this reduces the number of spilled registers in some cases and even eliminates spilling completely for some simple routines for i386 and AVR.
* Added a debug output of the number of spilled registers for each routine. This allows to easily compare results after changes in spilling algorithms.

e6b89c98f5 * Changed tsuperregisterworklist.get() to always return the last item from the list. 
* Reversed sort order of simplifyworklist so nodes with most interferences will get their colors first.
    Since degree of nodes in simplifyworklist before sorting is always
    less than the number of usable registers this should not trigger spilling
    and should lead to a better register allocation in some cases.

  After these changes sysutils.o for i386-win32 is 80 bytes less. :)

c455e942e5 * Try to avoid spilling of an imm register if it contains a value loaded from an already spilled imm register. It likely leads to an endless loop and the register allocation fails. 
This fixes the register allocation for i8086 when handling registers for very constrained instructions such as "mov ireg1,[ireg2+ireg3]". 
    Here ireg2 can be only BX or BP. So in most cases only BX is available. When ireg2 is spilled, its value must be loaded to BX only.
    Coloring of the ireg which holds the spilled value must be as early as possible to be able to assign BX to this ireg.
    This fix should also help register allocation for other constrained/old CPUs.
