...which can act as either a rewriter or a non-rewriter that emits warnings.
Also added COMPILER_PLUGIN_WARNINGS_ONLY=X to demote warnings from plugin X from
errors to warnings, even under --enable-werror.

...as MSVC would warn about those anyway (at least about cases that do not
compare against literal sal_True/sal_False, but warning even about those helped
clean up lots of redundant
if (foo == true)
instead of just
if (foo)
etc. across the code base).

...as they are often enough errors, like a typo in brace placement in
if (foo == (FOO || bar == BAR) && baz)
or a literal true passed as an argument to a function that rather expects an
integer bit mask, etc. The plugin is smart enough to detect interaction with
logically boolean return/parameter types of C functions that use [unsigned] int
instead, and knows the relevant boolean typedefs (sal_Bool, gboolean, etc.).
