Adjust some analyzer tests to place widely shared inputs inside of an
'Inputs' subdirectory.

The general desire has been to have essentially all of the non-test
input files live in such directories, with some exceptions for obvious
and common patterns like 'foo.c' using 'foo.h'.

This came up because our distributed test runner couldn't find some of
the headers, for example with stl.cpp.

No functionality changed, just shuffling around here.
