---------------------------------+-------------------------------
 presently, -emit-inline-file will not emit a file, and will delete one if
 it exists, if there are no exported procedures that can be inlined. this
 means in a pattern where you always emit for every -unit, and always
 consult for every -uses, compilation will halt if a file isn't found

 it's a matter of opinion what the right thing to do here is, but I'm
 inclined to think a file should always be emitted if the flag is passed,
 even it's empty, because:
 * it's consistent with how -emit-types-file behaves
 * usage of the flag indicates user intent to create the file
 * "absence of evidence isn't evidence of absence"--the existence of an
 empty file is an affirmative statement there is nothing to inline

 note the deletion/omission behavor was added on purpose in 2010, so this
 isn't accidental, but I'm not sure the reasoning

 tested on platform=LINUX
