Warn about "X && 0x1000" saying that the user may mean "X & 0x1000".
Probably only want to do this for hex immediates. Likewise for ||.

Lexer-related diagnostics should point to the problematic character, not the
start of the token. For example:
int y = 0000\
00080;
diag.c:4:9: error: invalid digit '8' in octal constant
int y = 0000\
^
should be:
diag.c:4:9: error: invalid digit '8' in octal constant
00080;
^
This specific diagnostic is implemented, but others should be updated.
