[lld] Glob-based BP compression sort groups (#185661)
Add
--bp-compression-sort-section=<glob>[=<layout_priority>[=<match_priority>]]
to let users split input sections into multiple compression groups, run
balanced partitioning independently per group, and leave out sections
that are poor candidates for BP. This replaces the old coarse
--bp-compression-sort with a more explicit, user-controlled one.
In ELF, the glob matches input section names (.text.unlikely.cold1). In
Mach-O, it matches the concatenated segment+section name (__TEXT__text).
layout_priority controls group placement in the final layout.
match_priority resolves conflicts when multiple globs match the same
section: explicit priority beats positional matching, and among
positional specs the last match wins.
A CRTP hook getCompressionSubgroupKey() allows backends to further
subdivide glob groups into independent BP instances. This allows Mach-O

[RISCV] Fix stackmap shadow trimming NOP size for compressed targets (#189774)
The shadow trimming loop in LowerSTACKMAP hardcoded a 4-byte decrement
per instruction, but when Zca is enabled NOPs are 2 bytes. Use NOPBytes
instead of the hardcoded 4 so the shadow is correctly trimmed on
compressed targets.

[RISCV] Relax VL constraint in convertSameMaskVMergeToVMv (#189797)
When converting a PseudoVMERGE_VVM to PseudoVMV_V_V, we previously
required MIVL <= TrueVL to avoid losing False elements in the tail.
Relax this constraint when the vmerge's False operand equals its
Passthru operand and the True instruction's tail policy is TU
(tail undisturbed). In this case, True's tail lanes preserve its
passthru value (which equals False and Passthru), so the conversion
is safe even when MIVL > TrueVL.

[scudo] Fix reallocate for MTE. (#190086)
For MTE, we can't use the whole size or we might trigger a segfault.
Therefore, use the exact size when MTE is enabled or the exact usable
size parameter is true.
Also, optimize out the call to getUsableSize and use a simpler
calculation.
Fix case of normal numbers starting with a highword of 0x0 for m68k.
In the case of mac68k there can still be normal numbers with a highword
value of 0. This differs from x86 where they would be considered denormals.
