Daniel Dunbar 58194307c1 build: Add support for a SHOW_DIAGNOSTICS build variable.
If enabled, this will attempt to use the CC_LOG_DIAGNOSTICS feature I dropped
into Clang to print a log of all the diagnostics generated during an individual
build (from the top-level). Not sure if this will actually be useful, but for
now it is handy for testing the option.
