Peter Collingbourne 16d8086f72 Implement categories for special case lists. ... A special case list can now specify categories for specific globals, which can be used to instruct an instrumentation pass to treat certain functions or global variables in a specific way, such as by omitting certain aspects of instrumentation while keeping others, or informing the instrumentation pass that a specific uninstrumentable function has certain semantics, thus allowing the pass to instrument callers according to those semantics. For example, AddressSanitizer now uses the "init" category instead of global-init prefixes for globals whose initializers should not be instrumented, but which in all other respects should be instrumented. The motivating use case is DataFlowSanitizer, which will have a number of different categories for uninstrumentable functions, such as "functional" which specifies that a function has pure functional semantics, or "discard" which indicates that a function's return value should not be labelled.
