[Help-smalltalk] [RFC PATCH 0/2] fix overflow check for #basicAt: and #basicAt:put:

[Paolo Bonzini]

Holger found an overflow bug in #basicAt: and #basicAt:put:,
which breaks classes that have both fixed and indexed instance
variables.  The following patches fix it; I didn't yet add
testcases or attempted to deal with the fallout: as expected,
the delays.st test starts failing as it does under the JIT.
DebugTools also fails due to the same access with index -1.

Paolo Bonzini (2):
  tweak index_oop_spec and index_oop_put_spec index computations
  fix overflow check for #basicAt: and #basicAt:put:
