DARWIN: Correct size of arm64 LWP jmp_buf_type to 64-bits
Since the introduction of arm64 support, the LWP jmp_buf_type has been
32 bits. This causes LWP programs to fail whenever an LWP stack happens
to be allocated above the 4G line:
stackcheck = 50462976: stack = 50462976
topstack = 0x50013ff0: stackptr = 0x150008000: stacksize = 0xc000
Fri Mar 14 10:22:04 2025 LWP: stack overflow in process IO MANAGER!
from Overflow_Complain()
Abort trap: 6
This is due to 32-bit truncation of the LWP context topstack value, as
seen in the output above: topstack is reported as 0x50013ff0, but it
should be 0x150013ff0.
Define the size of jmp_buf_type to be uint64 for AFS_ARM64_DARWIN_ENV.
Note: This problem is most frequently observed in cmdebug and bos.
