Add option to format a whole file using git-clang-format (#204336)

Today, git-clang-format will only format lines which have been modified.
However, in some cases, that's not sufficient to get a "clean" file
which would be unmodified by running `clang-format` manually.

I've got a minimal repro using the default clang-format rules. Setup a
new git repository and create a commit with an empty file:

```
mkdir /tmp/bla
cd /tmp/bla
git init
touch t.cpp
git add t.cpp
git commit -m "V1"
```

Add a line to that file containing a comment:
```
echo "int x = 0; // Comment describing x" > t.cpp
git add t.cpp
git clang-format --staged # Reports "clang-format did not modify any files"
git commit -m "V2"
```

There's nothing wrong with this file yet, and it's working as expected.
Problem arises when we add a new line with a comment which is not
aligned with the comment we've already added:

```
echo "int longerThanX = 0; // Should cause above to become aligned" >> t.cpp
git add t.cpp
git clang-format --staged # Reports "clang-format did not modify any files"
```

git-clang-format didn't change the staged file here as it's only
inspecting the modified lines, but according to the default formatting
rules, this new line actually has an effect on the preceding line. i.e.,
if you run `clang-format t.cpp`, you'll see that whitespace is added
before the "Comment describing x" to align with the "Should cause..."

It's not limited to _just_ the preceding line (e.g. in the case where we
have multiple lines like the first with comments which become
unaligned,) so can't just add more lines of context to the diff. This PR
just adds an option to format the whole file, instead of just the
modified sections.

[lldb][test] Skip the JSON symbol file test on WebAssembly (#213407)

A JSON symbol file requires the UUID of the module it describes, and a
WebAssembly module carries no UUID.

[X86AsmBackend] Define reset() hook (#213409)

Noticed when reviewing #175830: MCObjectStreamer::reset frees the
fragments PendingBA and PrevInstPosition point into, but X86AsmBackend
keeps them. Define the hook.

Git commit b94b699857a5de41b0def1cffca6908e584be27f by GitHub (on behalf of Alexander Richardson) on 01/08/2026 at 05:45..
[RISCV] Fix ISCVISAInfo::computeDefaultABI() result for xcheriot (#212129)

XCheriot was not considered in this function, so RV32E+XCheriot
defaulted
to ilp32e instead of cheriot when no -target-abi was given.

Since this function does not have unit test coverage, this adds new
tests
for the ABI inference functions: RISCVISAInfo::computeDefaultABI() and
RISCVABI::computeTargetABI.
