Log Message:
lint: improve support for __int128_t and __uint128_t

For the .ln files, I chose the letter 'J' to represent the 128-bit
integer types since it is close to 'I' for int.  The naming of 'L' for
'long' is obvious, but 'Q' for 64-bit integers is a quad-16-bit word,
which is an unusual measurement unit nowadays.  One benefit of choosing
'J' is that the next letter, 'K' can then be used for 256-bit integer
types.

Support for 128-bit integer types is still very basic.  Plus, it is only
supported on LP64 platforms, which means that lint cannot be
cross-compiled to check for an LP64 platform while running on an ILP32
platform.
