[BasicAA] Fix BatchAA results for phi-phi assumptions

Change the way NoAlias assumptions in BasicAA are handled. Instead of
handling this inside the phi-phi code, always initially insert a
NoAlias result into the map and keep track whether it is used.
If it is used, then we require that we also get back NoAlias from
the recursive queries. Otherwise, the entry is changed to MayAlias.

Additionally, keep track of all location pairs we inserted that may
still be based on assumptions higher up. If it turns out one of those
assumptions is incorrect, we flush them from the cache.

The compile-time impact for the new implementation is significantly
higher than the previous iteration of this patch:
However, it should avoid the exponential runtime cases we run into
if we don't cache assumption-based results entirely.

This also produces better results in some cases, because NoAlias
assumptions can now start at any root, rather than just phi-phi pairs.
This is not just relevant for analysis quality, but also for BatchAA
consistency: Otherwise, results would once again depend on query order,
though at least they wouldn't be wrong.

This ended up both more complicated and more expensive than I hoped,
but I wasn't able to come up with another solution that satisfies all
the constraints.

[clang-offload-bundler] Add option -list

clang-offload-bundler is not only used by clang driver
to bundle/unbundle files for offloading toolchains,
but also used by out of tree tools to unbundle
fat binaries generated by clang. It is important
to be able to list the bundle IDs in a bundled
file so that the bundles can be extracted.

This patch adds an option -list to list bundle
ID's in a bundled file. Each bundle ID is separated
by new line. If the file is not a bundled file
nothing is output and returns 0.

[hip] Fix HIP version parsing.

- Need trimming before parsing major or minor version numbers. This's required
  due to the different line ending on Windows.
- In addition, the integer conversion may fail due to invalid char. Return that
  parsing function return `true` when the parsing fails.
