Summary: Also update the help modifier (h) so that it works as a modifier and not just as a standalone `h`. For example, `llvm-ar h` prints the help message, but `llvm-ar xh` currently prints `unknown option h`.

When on windows gnu-ar treats member names as case insensitive. This

Summary:
llvm-ar's mri-utf8.test test relies on the en_US.UTF-8 locale to be
installed for its last RUN line to work. If not installed, the unicode
string gets encoded (interpreted) as ascii which fails since the most
significant byte is non zero. This commit changes the test to only rely
on the system being able to encode the pound sign in its default
encoding (e.g. UTF-16 for Microsoft Windows) by always opening the file
via input/output redirection. This avoids forcing a given locale to be
present and supported. A Byte Order Mark is also added to help
recognizing the encoding of the file and its endianness.

Summary:
llvm-ar's mri-utf8.test test relies on the en_US.UTF-8 locale to be
installed for its last RUN line to work. If not installed, the unicode
string gets encoded (interpreted) as ascii which fails since the most
significant byte is non zero. This commit changes the call to open to
use a binary literal of the UTF-8 encoding for the pound sign instead,
thus bypassing the encoding step.
Note that the echo to create the <pound sign>.txt file will work
regardless of the locale because both the shell and the echo (in case
it's not a builtin of the shell concerned) only care about ascii
character to operate. Indeed, the mri-utf8.test file (and in particular
the pound sign) is encoded in UTF-8 and UTF-8 guarantees only ascii
characters can create bytes that can be interpreted as ascii characters
(i.e. bytes with the most significant bit null).
So the process to break down the filename in the line goes something
along:
- find an ascii chevron '>'
- find beginning of the filename by removing ascii space-like characters
- find ascii newline character indicating the end of the redirection (no
semicolon ';', closing curly bracket '}' or parenthesis ')' or the
like
- create a file whose name is made of all the bytes in between beginning
and end of filename *without interpretting them*

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.

Currently, YAML has the following syntax for describing the symbols:
Symbols:
Local:
LocalSymbol1:
...
LocalSymbol2:
...
...
Global:
GlobalSymbol1:
...
Weak:
...
GNUUnique:
I.e. symbols are grouped by their bindings. That is not very convenient,
because:
It does not allow to set a custom binding, what can be useful for producing
broken/special outputs for test cases. Adding a new binding would require to
change a syntax (what we observed when added GNUUnique recently).
It does not allow to change the order of the symbols in .symtab/.dynsym,
i.e. currently all Local symbols are placed first, then Global, Weak and GNUUnique
are following, but we are not able to change the order.
It is not consistent. Binding is just one of the properties of the symbol,
we do not group them by other properties.
It makes the code more complex that it can be. This patch shows it can be simplified
with the change performed.
The patch changes the syntax to just:
Symbols:
Symbol1:
...
Symbol2:
...
...
With that, we are able to work with the binding field just like with any other symbol property.

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).
