Sanjoy Das 3336f681e3 [Verifier] Add verification for TBAA metadata Summary: This change adds some verification in the IR verifier around struct path TBAA metadata. Other than some basic sanity checks (e.g. we get constant integers where we expect constant integers), this checks: - That by the time an struct access tuple `(base-type, offset)` is "reduced" to a scalar base type, the offset is `0`. For instance, in C++ you can't start from, say `("struct-a", 16)`, and end up with `("int", 4)` -- by the time the base type is `"int"`, the offset better be zero. In particular, a variant of this invariant is needed for `llvm::getMostGenericTBAA` to be correct. - That there are no cycles in a struct path. - That struct type nodes have their offsets listed in an ascending order. - That when generating the struct access path, you eventually reach the access type listed in the tbaa tag node.

This directory contains testcases that the verifier is supposed to detect as
malformed LLVM code.  Testcases for situations that the verifier incorrectly
identifies as malformed should go in the test/Assembler directory.
