Since GNU ar 2.31, the 't' operation prints member offsets beside file

The internal representation of llvm-ar archives uses linux style slashes
for paths, no matter the OS. In the case of windows this meant file
paths input intending to match existing members would only match if
linux style slashes where used. This change allows either slash
direction to be input by the user.
This change includes removing an unnecessary call to normalisePath and
moving the call of another.

Summary:
For the most part this consists of replacing ${LLVM_TARGETS_TO_BUILD} with
some combination of AllTargets* so that they depend on specific components
of a target backend rather than all of it. The overall effect of this is
that, for example, tools like opt no longer falsely depend on the
disassembler, while tools like llvm-ar no longer depend on the code
generator.
There's a couple quirks to point out here:
* AllTargetsCodeGens is a bit more prevalent than expected. Tools like dsymutil
seem to need it which I was surprised by.
* llvm-xray linked to all the backends but doesn't seem to need any of them.
It builds and passes the tests so that seems to be correct.
* I left gold out as it's not built when binutils is not available so I'm
unable to test it

Summary:
GNU ar supports the 'N' count modifier for the extract (x) and delete (d) operations. When an archive contains multiple members with the same name, this can be used to extract (or delete) them individually. For example:
```
$ llvm-ar t archive.a
foo
foo
$ llvm-ar x archive.a
-> Writes foo twice, overwriting it the second time :( :(
$ llvm-ar xN 1 archive.a foo && mv foo foo.1
$ llvm-ar xN 2 archive.a foo && mv foo foo.2
-> Write foo twice, renaming it in between invocations to preserve all versions
```

Summary:
GNU ar has a `P` modifier that changes filename comparisons to use full paths instead of the basename. As noted in the GNU docs, regular archives are not created with full path names, so P is used to deal with archives created by other archive programs (e.g. see the updated `absolute-paths.test` test case).
Since thin archives use full path names -- paths are relative to the archive -- it seems very error prone to not imply P when dealing with thin archives, so P is implied in those cases. (I think this is a deviation from GNU ar that makes sense).
This fixes PR37436 via https://github.com/ClangBuiltLinux/linux/issues/33.

Summary:
When adding one thin archive to another, we currently chop off the relative path to the flattened members. For instance, when adding `foo/child.a` (which contains `x.txt`) to `parent.a`, when flattening it we should add it as `foo/x.txt` (which exists) instead of `x.txt` (which does not exist).
As a note, this also undoes the `IsNew` parameter of handling relative paths in r288280. The unit test there still passes.
This was reported as part of testing the kernel build with llvm-ar: https://patchwork.kernel.org/patch/10767545/ (see the second point).

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Summary:
Normal behavior for GNU ar is to flatten thin archives when adding them to another thin archive, i.e. add the members directly instead of nesting the archive.
Some refactoring done as part of this patch to ease things:
- Consolidate `addMember`/`addLibMember` methods
- Rename `addMember` to `addChildMember` to make it more visibly different at the call site that an archive child is passed instead of a regular member
- Pass in a separate vector and splice it back into position instead of passing a vector + optional Pos (which makes expanding libs tricky)
This fixes PR37530 as raised by https://github.com/ClangBuiltLinux/linux/issues/279.

Summary:
The POSIX spec says:
```
If the −t option is used with the −v option, the standard output format shall be:
"%s %u/%u %u %s %d %d:%d %d %s\n", <member mode>, <user ID>,
<group ID>, <number of bytes in member>,
<abbreviated month>, <day-of-month>, <hour>,
<minute>, <year>, <file>
where:
...
<abbreviated month>
Equivalent to the format of the %b conversion specification format in date.
<day-of-month>
Equivalent to the format of the %e conversion specification format in date.
<hour> Equivalent to the format of the %H conversion specification format in date.
<minute> Equivalent to the format of the %M conversion specification format in date.
<year> Equivalent to the format of the %Y conversion specification format in date.
```
This actually used to be the format printed by llvm-ar. It was apparently accidentally changed (see r207385 followed by comments in r207387). This makes it conform to GNU ar for easier replacement.

Summary:
Add an overload to sys::fs::setLastModificationAndAccessTime that allows setting last access and modification times separately. This will allow tools to use this API when they want to preserve both the access and modification times from an input file, which may be different.
Also note that both the POSIX (futimens/futimes) and Windows (SetFileTime) APIs take the two timestamps in the order of (1) access (2) modification time, so this renames the method to "setLastAccessAndModificationTime" to make it clear which timestamp is which.
For existing callers, the 1-arg overload just sets both timestamps to the same thing.

This breaks the OpenFlags enumeration into two separate
enumerations: OpenFlags and CreationDisposition. The first
controls the behavior of the API depending on whether or not
the target file already exists, and is not a flags-based
enum. The second controls more flags-like values.
This yields a more easy to understand API, while also allowing
flags to be passed to the openForRead api, where most of the
values didn't make sense before. This also makes the apis more
testable as it becomes easy to enumerate all the configurations
which make sense, so I've added many new tests to exercise all
the different values.
