[PATCH] Bug 15109: Implement -Wdouble-promotion for clang

[George Burgess IV via cfe-commits]

Committed as r251588 -- thanks again!

FYI: I'm assuming that you meant to change the test to
warn-double-promotion.c instead of leaving it as warn-double-promotion.cpp,
so I made that fix for you prior to committing. If this is isn't something
you wanted, please let me know. :)
