In order to solve the recurring overflow issues with the memory API,
introduce a 128-bit integer type to hold sizes (range 0 - 2^64) and
intermediates. While the patchset does reduce readability, I believe
it is the only way to prevent overflows emerging in unlikely places in
the code.
Avi Kivity (2):
Add support for 128-bit arithmetic
memory: use 128-bit integers for sizes and intermediates
