std: check for overflow in dumpStackTraceFromBase
same change as [68e26a2ceea85a1] "std: check for overflow in writeCurrentStackTrace"
On arm64 macOS, the address of the last frame is 0x0 rather than
a positive value like 0x1 on x86_64 macOS, therefore, we overflow
an integer trying to subtract 1 when printing the stack trace. This
patch fixes it by first checking for this condition before trying
to subtract 1.
Same behaviour on i386-windows-msvc.
Note that we do not need to signal the `SignalIterator` about this
as it will correctly detect this condition on the subsequent iteration
and return `null`, thus terminating the loop.
