* GetNextReg(), used by 16-bit and 8-bit code generators (i8086 and avr) moved
...
from cpubase unit to a method in the tcg class. The reason for doing that is
that this is now a standard part of the 16-bit and 8-bit code generators and
moving to the tcg class allows doing extra checks (not done yet, but for
example, in the future, we can keep track of whether there was an extra
register allocated with getintregister and halt with an internalerror in case
GetNextReg() is called for registers, which weren't allocated as a part of a
sequence, therefore catching a certain class of 8-bit and 16-bit code
generator bugs at compile time, instead of generating wrong code).
- removed GetLastReg() from avr's cpubase unit, because it isn't used for
anything. It might be added to the tcg class, in case it's ever needed, but
for now I've left it out.
* GetOffsetReg() and GetOffsetReg64() were also moved to the tcg unit.

* Delete regvars unit.
...
This unit was empty unless OLDREGVARS macro was set,
but this does not compile and no change has been made since 2011.
* Remove regvars from all _USES clauses.
