these should disappear.
Here is a more readable list than is in the diff:
W options: -Wall, -Wcast-align, -Wchar-align, -Wchar-subscripts,

-Wunused-function, -Wunused-label, -Wunused-value, -Wunused-variable,
-Wwrite-strings.
f options: -fasm-blocks, -fmessage-length=.

are forwarded to GCC.
- The later is unfortunate, as it prevents us from generally warning
about anything interesting on platforms that use a generic
toolchain. However, we can't do much better without significantly
complicating things, and generally we should have proper tool chain
definitions.

- Make InputInfo a variant of filename, pipe, input argument,
nothing.
- Leave a FIXME in InputInfo that this should be revisited.

if our usual methods fail. This isn't necessary for running the tool,
but improves the accuracy of logging output.
Also, have GCC tools lookup gcc program path.
