[foreign-abi] Cannot automatically merge foreign-memaccess to foreign-abi

[J.Duke]

Hi all,

this is an _automatically_ generated merge request to notify you that there are 2 commits from the branch
`foreign-memaccess`that can **not** be merged into the branch `foreign-abi`:

The following files contains merge conflicts:

- src/java.base/share/classes/java/lang/invoke/MemoryAccessVarHandleGenerator.java
- src/java.base/share/classes/java/lang/invoke/MethodHandleImpl.java
- src/java.base/share/classes/jdk/internal/access/JavaLangInvokeAccess.java
- src/jdk.incubator.foreign/share/classes/jdk/incubator/foreign/MemoryHandles.java
- src/jdk.incubator.foreign/share/classes/jdk/internal/foreign/LayoutPath.java
- test/jdk/java/foreign/TestAddressHandle.java

The following paragraphs will give an example on how to solve these merge conflicts and create a pull request to
integrate them. If you are using a workflow different from the one below, feel free to use that instead. It is
important that the title of the pull request you create is `Merge foreign-memaccess`, otherwise the bots will _not_
understand that the pull request you create is a "merge style" pull request.

The below commands should be run in a local clone of your [personal
fork](https://wiki.openjdk.java.net/display/skara#Skara-Personalforks) of the
[openjdk/panama-foreign](https://git.openjdk.java.net/panama-foreign) repository. These commands will allow you to view
and resolve the merge conflicts. Note that the name of the local branch in the commands,
`merge-foreign-memaccess-into-foreign-abi-f683a7fd`, is just an example, feel free to give the local branch any name
you prefer.

$ git checkout foreign-abi
$ git pull https://git.openjdk.java.net/panama-foreign foreign-abi
$ git checkout -b merge-foreign-memaccess-into-foreign-abi-f683a7fd
$ git pull https://git.openjdk.java.net/panama-foreign foreign-memaccess

When you have resolved the conflicts resulting from the `git pull` command above, run the following commands to create
a merge commit:

$ git add paths/to/files/with/conflicts
$ git commit -m 'Merge foreign-memaccess'

The commit message does not have to be `Merge foreign-memaccess`, but it is convenient for when you will create a pull
request. Many tools will by default use the commit message of the most recent commit on a branch as the title for a
pull request from that branch. This means that if you use the commit message `Merge foreign-memaccess` as the commit
message then the title of the pull request will (depending to tools used to create the pull request) be of a format
that the bots expect.

Proceed to [publish the local
branch](https://wiki.openjdk.java.net/display/SKARA/FAQ#FAQ-HowdoIpushalocalbranchtoaremoterepository?) and [create a
pull request](https://wiki.openjdk.java.net/display/SKARA/FAQ#FAQ-HowdoIcreateapullrequest?) towards the `foreign-abi`
branch in the [openjdk/panama-foreign](https://git.openjdk.java.net/panama-foreign) repository. The resulting pull
request can then integrated as usual once it has passed all required pre-integration checks.

Thanks,
J. Duke
