This removes BindName, putting name information directly on VarStorage.
As a side-effect of updating semantics_ir_test for this change, I also
noted that function bodies were being generated as invalid YAML so am
fixing that (just `{}` to `[]` bracketing, otherwise the test wouldn't
work anymore).
Because names are now available, I've updated lowering to use them for
vars.
In the SemIR formatter, the name is now repeated because it's a
parameter to VarStorage. I believe this is just default behavior, and
we'd have to special-case VarStorage to remove it because it's automatic
argument printing in action. On the balance, it felt like letting it
print was reasonable.
I've noted in places that the name on VarStorage is expected to be
optional, but am not adding support because I'd have no way of testing
it at present.
Add a textual IR format to the toolchain.
The exact details of the format are somewhat arbitrary right now, and I
expect them to change as we refine the semantics IR model, but at the
moment they're somewhat directly following the current structure of the
IR.
Semantics tests currently test both the "raw" format, which shows the
details of the representation, and the textual format, which is somewhat
higher level. We may want to revisit that decision once the textual
format is a bit more stable, and test only the textual format in most of
these tests, but for now it seems prudent to keep both sets of tests.

Allow interleaving of STDOUT and STDERR check lines. Put STDOUT lines
after the line they're attached to, and STDERR lines before. If no
STDOUT check line is attached to any line, then put them all at the end
of the file instead.
This is intended to better handle the case where stdout contains
unreplaced mentions of line numbers, and also reflects that stdout is
typically a consequence of the test rather than commentary on it, so
placing it after the test seems likely to read better.
