[clang] Fix assertion failures involving code completion with delayed default arguments and exception specifications (#203794)

Fixes #200879.

This patch fixes crashes when code completion is invoked immediately
after the declaration of a top-level class containing methods with
default arguments or exception specifications.

Default-argument case: https://godbolt.org/z/4G9nTfnGd
Exception-specification case: https://godbolt.org/z/8frEv8von

When code completion is triggered right after the class body, the
lookahead token is `tok::code_completion` when late parsing begins. The
token is saved to the cached token stream and `ConsumeAnyToken()` is
called to consume it, but `ConsumeAnyToken()` defaults to rejecting
completion tokens, which cuts off parsing. In the default-arguments path
(as reported in #200879), the assertion `Tok.is(tok::equal) && "Default
argument not starting with '='"` is triggered because `cutOffParsing()`
sets the current token to `eof`.

[M68k][MC] Generate some encoding tests for MOVE (#194269)

# Problem statement

Instruction encoding needs to be solid, as it's one of the foundations
that a target backend is built upon.

It's error-prone work, and tedious to write tests for.

Test coverage for M68k instruction encoding isn't exhaustive, and we've
had bugs in the past where instructions have not been encoded correctly.

# Proposed solution

Using the documentation at https://m680x0.github.io/doc/official-docs it
should be possible to write some scripts to generate encoding tests for
all the instructions.

[analyzer] Implement UseAfterLifetimeEnd checker (#205521)

Implemented the UseAfterLifetimEnd checker which is responsible for detecting lifetime safety violations involving the [[clang::lifetimebound]] annotation. This checker can catch violations in annotated code such as dangling pointer/reference bound to local variables that go out of scope. This checker is one of the reporting checkers that depend on the LifetimeModeling checker #205951. To detect dangling sources the checker queries the state at function exit points through the checkEndFunction callback. This checker does not handle lifetime issues where the code is unannotated.

Detailed work history of this checker can be found here: #200145

[clang][Driver] Include stdc-predef.h by default on musl

Match GCC behavior for musl-based Linux targets by implicitly passing
`-include stdc-predef.h` for non-freestanding compilations.

Unlike glibc, musl does not arrange for this header to be included through
its normal system headers. As a result, Clang may miss predefined C macros
provided by musl's stdc-predef.h unless users include it manually, while the
same code works with GCC.

Add Driver tests covering musl, non-musl, freestanding, preprocessed input,
missing-header diagnostics, and actual macro visibility.

This patch is based on: https://reviews.llvm.org/D137043 and
slightly tweaks it, as the code has drifted since 2023 when
that was authored.

[OpenMP][Clang] Fix parsing of num_teams lower-bound modifier (#205700)

PR #180608 added parsing for the `lower-bound` modifier in the
`num_teams` clause. However, the lower bound expression is handled by
adding it to the first position of the clause's varlist, which is the
list that holds the number of teams for each dimension when `ompx_bare`
is specified. Given that the interpretation of the varlist depends on
its length, the following `ompx_bare` cases are broken:
- `#pragma omp target teams ompx_bare num_teams(11,10)` is interpreted
as a lower-bound and upper-bound, triggering the error "_lower bound is
greater than upper bound in 'num_teams' clause_".
- `#pragma omp target teams ompx_bare num_teams(1,2)` is interpreted as
`num_teams(1:2)` when printing the AST.

This commit fixes the collision by storing the lower bound separated from
the list of upper-bounds. This change is necessary for landing the
upcoming support for multidimensional team spaces (OpenMP 6.1) through
the `dims` modifier.

reduced from a csmith-generated C program. And I believe this problem
also exists in real-world programs.
