(#75937)
If a virtual function is declared with `noexcept`, functions that
override this function in the derived classes must be declared with
`noexcept` as well. This PR updates code completion in clang Sema. It
adds `noexcept` specifier to override functions in the code completion
result if the functions override a `noexcept` virtual function.

Tests where the RUN-lines/CHECK-ed output refer to line numbers in the test
file are a maintenance burden, as inserting text in the appropriate place
invalidates all the subsequent line numbers.
Lit supports %(line+n) for this, and FileCheck supports [[@LINE+N]].
But many existing tests don't make use of it and still need to be modified.
This commit adds a script that can find line numbers in tests according to a
regex and replace them with the appropriate relative-line reference.
It contains some options to avoid inappropriately rewriting tests where absolute
numbers are appropriate: a "nearby" threshold and a refusal by default to
replace only some matched line numbers.
I've applied it to CodeComplete tests, this proves the concept but also are the
single worst group of tests I've seen in this respect.
These changes are likely to hit merge conflicts, but can be regenerated with:
```
find ../clang/test/CodeCompletion/ -type f | grep -v /Inputs/ | xargs ../llvm/utils/relative_lines.py --verbose --near=20 --pattern='-code-completion-at[ =]%s:(\\d+):' --pattern='requires fix-it: {(\d+):\d+-(\d+):\d+}'

Summary:
We put only part of the signature starting with a function name into "typed text"
chunks now, previously the whole signature was "typed text".
This leads to meaningful fuzzy match scores, giving better signals to
compare with other completion items.
Ideally, we would not display the result type to the user, but that requires adding
a new kind of completion chunk.

Summary:
In clangd we had a new type of completion suggestions for cpp
class/struct/unions that will show override signatures for virtual methods in
base classes. This patch implements it in sema because it is hard to deduce more
info about completion token outside of Sema and handle itchy cases.
See the patch D50898 for more info on the functionality.
In addition to above patch this one also converts the suggestion into a
CK_Pattern with whole insertion text as the name of the suggestion and factors
out CodeCompletionString generation for declerations so that it can be re-used
by others.
