[llvm-readelf][llvm-readobj] - Fix the indentation when printing dynamic tags.
This change is similar to one made for llvm-objdump in D72838.

llvm-readelf/llvm-readobj tools do not align the "Name/Value" column properly.
This patch adds a logic to calculate the size of indentation on fly
to fix such issues.

[DAG] Fold extract_vector_elt (scalar_to_vector), K to undef (K != 0)
This was unconditionally folding this to the source operand, even if the access was out of bounds. Use undef instead of the extract is not the first element.

This helps with some cases where 3-vectors are legalized and avoids processing the 4th component.

The INPUT_SECTION_FLAGS linker script command is used to constrain the
section pattern matching to sections that match certain combinations of

There are two ways to express the constraint.
withFlags: Section must have these flags.
withoutFlags: Section must not have these flags.

The syntax of the command is:
INPUT_SECTION_FLAGS '(' sect_flag_list ')'
sect_flag_list: NAME
| sect_flag_list '&' NAME

Where NAME matches a section flag name such as SHF_EXECINSTR, or the
integer value of a section flag. If the first character of NAME is ! then
it means must not contain flag.

We do not support the rare case of { INPUT_SECTION_FLAGS(flags) filespec }
where filespec has no input section description like (.text).

As an example from the ld man page:
  .text2 :  { INPUT_SECTION_FLAGS (!SHF_WRITE) *(.text) }
.text will match sections called .text that have both the SHF_MERGE and
.text2 will match sections called .text that don't have the SHF_WRITE flag.

The flag names accepted are the generic to all targets and SHF_ARM_PURECODE
as it is very useful to filter all the pure code sections into a single
program header that can be marked execute never.

[clangd] Fix rename for explicit destructor calls
When triggering rename of the class name in the code with explicit destructor
calls, rename fails. Consider the following piece of code:

class Foo;


Foo f;

`findExplicitReferences` will report two `ReferenceLoc` for destructor call:
one is comming from `MemberExpr` (i.e. destructor call itself) and would point
to the tilde:


And the second one is pointing to the typename and is coming from `TypeLoc`.


This causes rename to produce incorrect textual replacements. This patch
updates `MemberExpr` handler to detect destructor calls and prevents it
from reporting a duplicate reference.

[lld][RISCV] Print error when encountering R_RISCV_ALIGN
Unlike R_RISCV_RELAX, which is a linker hint, R_RISCV_ALIGN requires the
support of the linker even when ignoring all R_RISCV_RELAX relocations.
This is because the compiler emits as many NOPs as may be required for
the requested alignment, more than may be required pre-relaxation, to
allow for the target becoming more unaligned after relaxing earlier
sequences. This means that the target is often not initially aligned in
the object files, and so the R_RISCV_ALIGN relocations cannot just be
ignored. Since we do not support linker relaxation, we must turn these
into errors.

This reverts commit a8a9c8e0a11abc9ed4ed78fed528334371fedf87.

Each failure is really weird, but it makes sense to revert

AMDGPU: Don't create weird sized integers
There's no reason to introduce a new, unnaturally sized value

legalization. Avoids regression in a future patch.

The code doesn't apply the fix correctly to relocatable links. I could
try to fix the code that applies the fix, but it's pointless: we don't
actually know what the offset will be in the final executable. So just
ignore the flag for relocatable links.
