tests/lint: remove .exp files, as they have become redundant

Now that each lint1 test lists all generated diagnostics as 'expect'
comments, the information from the .exp files is no longer needed.  The
only information that gets lost is the order of the diagnostics, which
is mostly relevant for paired messages like 'inconsistent definition' +
'previous definition was here'.

tests/lint: test parsing of octal integer constants

tests/lint: test parsing of integer constants

The previous version of this test did not focus on the integer constants
but instead on conversions of function arguments.  The current test
covers several corner cases, such as non-decimal bases and all
combinations of suffixes.

This test does not cover lex_integer_constant completely since several
code paths are only reachable on 32-bit target platforms.

tests/lint: allow skipping individual tests

Depending on the platform, some tests do not make sense or produce
platform-dependent results.  Allow these tests to be marked as such.

For example, the test lex_integer.c only works on 64-bit platforms.
Therefore it is disabled on i386 for now since it prints different
warnings there.  Even better would be a "lint1-only-on-lpi32" toggle,
but that would need detection of 'sizeof(int)' at runtime.
