Since this is testing for an assertion failure, the test checks don't matter, but we might as well avoid unnecessary churn the next time someone modifies this test.

  [clang][ExprConstant] Fix crash on uninitialized base class subobject

This patch fixes the reported regression caused by D146358 through adding notes about an uninitialized base class when we diagnose uninitialized constructor.

This also changes the wording from the old one in order to make it clear that the uninitialized subobject is a base class and its constructor is not called.
Wording changes:
BEFORE: `subobject of type 'Base' is not initialized`
AFTER: `constructor of base class 'Base' is not called`

  [sanitizer] Intercept glibc 2.38 __isoc23_* functions

`strtol("0b1", 0, 0)` can be (pre-C23) 0 or (C23) 1.
`sscanf("0b10", "%i", &x)` is similar. glibc 2.38 introduced
`__isoc23_strtol` and `__isoc23_scanf` family functions for binary
compatibility.

When `_ISOC2X_SOURCE` is defined (implied by `_GNU_SOURCE`) or
`__STDC_VERSION__ > 201710L`, `__GLIBC_USE_ISOC2X` is defined to 1 and
these `__isoc23_*` symbols are used.

Add `__isoc23_` versions for the following interceptors:

* sanitizer_common_interceptors.inc implements strtoimax/strtoumax.
  Remove incorrect FIXME about https://github.com/google/sanitizers/issues/321
* asan_interceptors.cpp implements just strtol and strtoll. The default
  `replace_str` mode checks `nptr` is readable and `endptr` is writable.
  atoi reuses the existing strtol interceptor.
* msan_interceptors.cpp implements strtol family functions and their
  `_l` versions. Tested by lib/msan/tests/msan_test.cpp
* sanitizer_common_interceptors.inc implements scanf family functions.

The strtol family functions are spreaded, which is not great, but the
patch (intended for release/17.x) does not attempt to address the issue.

Add symbols to lib/sanitizer_common/symbolizer/scripts/global_symbols.txt to
support both glibc pre-2.38 and 2.38.

When build bots migrate to glibc 2.38+, we will lose test coverage for
non-isoc23 versions since the existing C++ unittests imply `_GNU_SOURCE`.
Add test/sanitizer_common/TestCases/{strtol.c,scanf.c}.
They catch msan false positive in the absence of the interceptors.

When folding a vmerge into its operands, if the resulting VL is smaller than

moved to the tail. In that case, we can't relax the tail policy to agnostic
when the merge operand is undefined, since we need to preserve these elements
past the new VL.

removed the warning group as the functionality is no longer a GNU
extension. However, users have asked for the warning group to be
supported so that code transitioning from Clang 16 to Clang 17 has an
easier migration path when compiling with -Werror. This patch restores
the warning group, but as an ignored warning group because the
functionality is now always considered to be a C extension rather than
a GNU extension. This allows users to do:

  -Werror -pedantic -Wno-gnu-empty-intializer -Wno-c2x-extensions

to silence the diagnostics in both Clang 16 and Clang 17.
