One of the defining features of the SVE ACLE types is that they
are "sizeless"; see the SVE ACLE spec:
https://developer.arm.com/docs/100987/0000/arm-c-language-extensions-for-sve
or the email message:
http://lists.llvm.org/pipermail/cfe-dev/2019-June/062523.html
for a fuller definition of what that means.
This patch adds two associated type queries:
- isSizelessBuiltinType asks specifically about types that are built
into clang. It is effectively an enum range check.
- isSizelessType instead tests for any type that has the "sizeless" type
property. At the moment it only returns true for the built-in types,
but it seems better not to hard-code that assumption throughout
the codebase. (E.g. we could in principle support some form of
user-defined sizeless types in future. Even if that seems unlikely
and never actually happens, the possibility at least exists.)
