[dsymutil] dsymutil produces broken lines info (probably) with LTO on mac
This patch fixes #60307 issue. The 8bb4451 introduces the possibility
to unite overlapped or adjacent address ranges to keep address ranges
in an unambiguous state. The AddressRangesMap is used to normalize
address ranges. The AddressRangesMap keeps address ranges and the value
of the relocated address. For intersected range, it creates a united
range that keeps the last inserted mapping value. The same for adjusted ranges.
While it is OK to use the last inserted mapping value for intersected ranges
(as there is no way how to resolve ambiguity) It is not OK to use the
last inserted value for adjacent address ranges. Currently, two following
address ranges are united into a single one:
{0,24,17e685c} {24,d8,55afe20} -> {0,d8,55afe20}
To avoid the problem, the AddressRangesMap should not unite adjacent address ranges
with different relocated addresses. Instead, it should leave adjacent address ranges
as separate ranges. So, the ranges should look like this:

Summary:
This patch introduces a mechanism to check the code object version from the module flag, This avoids checking from command line.
In case the module flag is missing, we use the current default code object version supported in the compiler.
For tools whose inputs are not IR, we may need other approach (directive, for example) to check the code
object version, That will be in a separate patch later.
For LIT tests update, we directly add module flag if there is only a single code object version associated with all checks in one file.

[C++20] [Modules] Pop Expression Evaluation Context when we skip its body during parsing
Close https://github.com/llvm/llvm-project/issues/60275
The root cause of issue 60275 is the imbalance of
PushExpressionEvaluationContext() and PopExpressionEvaluationContext().
See
https://github.com/llvm/llvm-project/blob/
f1c4f927f7c15b5efdc3589c050fd0513bf6b303/clang/lib/Parse/Parser.cpp#L1396-L1437
We will PushExpressionEvaluationContext() in ActOnStartOfFunctionDef()
in line 1396 and we should pop it in ActOnFinishFunctionBody later.
However if we skip the function body in line 1402, the expression
evaluation context will not be popped. Then here is the issue report. I
fix the issue by inserting codes to pop the expression evaluation
context explicitly if the function body is skipped. Maybe this looks
like an ad-hoc fix. But if we want to fix this in a pretty way, we
should refactor the current framework for pushing and popping expression
evaluation contexts. Currently there are 23
PushExpressionEvaluationContext() callsities and 21
PopExpressionEvaluationContext() callsites in the code. And it seems not
easy to balance them well and fast. So I suggest to land this fix first.
At least it can prevent the crash.

[RISCV][Driver] Add -mrvv-vector-bits= option similar to -msve-vector-bits=
This option will control the vscale min/max.
I have left out the '+' support that SVE supports for now. We already
have minimum controlled by the Zvl*b extension so this didn't seem that
useful.
I've added "scalable" from SVE to allow the option to be cancelled later on
command line. Though this name might make less sense for RISC-V since
the word "scalable" does not appear in the V spec. Maybe something like
"unknown" or "runtime" or "variable" would be better?
In addition to "scalable", 64, 128, 256, 512, ..., 65536, I have added an extra
value "zvl" that will use the value from Zvl*b as the min and max.
This avoids repeating the numeric value in two places or to get
min/max from -mcpu.
The primary effect of this option today is simplification of stack
address calculations for RVV vectors and avoiding the use of
vrgatherei16 in some cases if we know there are less than 256 elements.

7e7013c5d4b1b3996c8dba668c5a94bb33b2999b,
internal glibc macros were used to determine if C2X extensions are enabled.
Specifically, a check for whether `__GLIBC_USE` is defined and whether
`__GLIBC_USE(ISOC2X)` is non-0 was added. `__GLIBC_USE` is an internal
detail of the glibc implementation that may be changed or removed in the
future potentially leading to inconsistency or compilation failures. This
change removes the use of the internal glibc macro to avoid such problems.
Unfortunately, without another mechanism to determine if C2X extensions are
enabled, this removal will result in inconsistent declarations of the
c8rtomb() and mbrtoc8() functions; when C++ char8_t support is not enabled, but
C2X extensions are, these functions will be declared in the global namespace
but not in the std namespace. This situation will improve when C23 support
is finalized and the check can be re-implemented using `__STDC_VERSION__`.

2. Widening the v2i32 result type
The result will be incorrect because the legalizer will promote
