[PATCH] Capability attributes on a typedef

[Aaron Ballman]

This patch allows a capability attribute to be declared on a typedef
declaration (as a declaration attribute, not a type attribute). Eg)
typedef int __attribute__((capability("role"))) ThreadRole;

This is necessary for a WIP for Boolean expressions involving
capability attributes in C, where there are not operator overloads
that we can use. Eg) void func(void)
__attribute__((requires_capability(!SomeCap)));

This patch removes an existing diagnostic because it no longer
applies, which is why there is a fair amount of testcase churn.
