[ELF] Add target-specific relocation scanning for ARM (#182440)

Implement ARM::scanSectionImpl, following the pattern established for
AArch64 and other targets. This merges the getRelExpr and TLS handling
for SHF_ALLOC sections into the target-specific scanner, enabling
devirtualization and eliminating abstraction overhead.

- Inline relocation classification into scanSectionImpl with a switch
  on relocation type, replacing the generic rs.scan() path.
- Use processR_PC/processR_PLT_PC for common PC-relative and PLT
  relocations.
- Handle TLS inline: checkTlsLe for TLS LE, handleTlsIe<false> for
  TLS IE (no IE-to-LE optimization for ARM), and direct flag/reloc
  emission for TLS GD/LD (no GD/LD optimization for ARM).
- Set hasGotOffRel for R_GOTREL/R_GOTONLY_PC relocations.
- Simplify getRelExpr to only handle relocations needed by
  relocateNonAlloc and preprocessRelocs.

[llvm-mca][Darwin] Fix crash on .subsections_via_symbols in asm input (#182694)

## Summary

This PR fixes an llvm-mca crash on Darwin assembly containing
`.subsections_via_symbols`. The directive is forwarded by
`DarwinAsmParser` to `emitSubsectionsViaSymbols()`, which crashes when
it hits the base `MCStreamer` `llvm_unreachable` path. The fix adds a
no-op override in `llvm/tools/llvm-mca/CodeRegionGenerator.h`, scoped to
llvm-mca only

## Problem manifestation

I ran across this while tinkering around with making an interactive
interpreter/code analyzer and implementing apple silicon support.

## Root cause

- `DarwinAsmParser::parseDirectiveSubsectionsViaSymbols` calls

[BOLT] Always place new PT_LOAD after existing ones (#182642)

Insert new PT_LOAD segments right after the last existing PT_LOAD in the
program header table, instead of before PT_DYNAMIC or at the end. This
maintains the ascending p_vaddr order required by the ELF specification.

Previously, new segments could end up breaking PT_LOAD p_vaddr order
when PT_LOAD segments followed PT_DYNAMIC or PT_GNU_STACK. This lead to
runtime loader incorrectly assessing dynamic object size and silently
corrupting memory.

[clang-format] Add per-operator granularity for BreakBinaryOperations (#181051)

## Summary

Extend `BreakBinaryOperations` to accept a structured YAML configuration
with per-operator break rules and minimum chain length gating via
`PerOperator`.

- **Per-operator rules**: specify break style (`Never`, `OnePerLine`,
`RespectPrecedence`) for specific operator groups
- **Minimum chain length**: only trigger breaking when a chain has N or
more operators
- **Fully backward-compatible**: the simple scalar form
(`BreakBinaryOperations: OnePerLine`) behaves identically to the current
enum value

[profcheck][CVP] Adding 'unknown' branch weights for `urem` expansion in CVP (#180637)

This change ensures that !prof metadata is preserved and scaled
appropriately when the `CorrelatedValuePropagation` (CVP) pass expands
an expensive `urem` instruction into a sequence of `icmp`, `select`, and
`sub`.

In the RP, we add the `unknown`(50/50) branch weights for the new
`select` based on the original instruction's profile data.
