Aaron Ballman 19e984ef8f Properly print unnamed TagDecl objects in diagnostics
The diagnostics engine is very smart about being passed a NamedDecl to
print as part of a diagnostic; it gets the "right" form of the name,
quotes it properly, etc. However, the result of using an unnamed tag
declaration was to print '' instead of anything useful.

This patch causes us to print the same information we'd have gotten if
we had printed the type of the declaration rather than the name of it,
as that's the most relevant information we can display.

[clang][NFC] Add a test for __attribute__((flag_enum)) with an unnamed enumeration. 2020-07-26 17:24:43 +01:00
David Majnemer c10b8381f7 Update tests touched by r249656
These test updates almost exclusively around the change in behavior
around enum: enums without a definition are considered incomplete except
when targeting MSVC ABIs.  Since these tests are interested in the
'incomplete-enum' behavior, restrict them to %itanium_abi_triple.

Alexis Hunt 724f14e75c Create a new 'flag_enum' attribute.
This attribute serves as a hint to improve warnings about the ranges of
enumerators used as flag types. It currently has no working C++ implementation
due to different semantics for enums in C++. For more explanation, see the docs
and testcases.
