a087dea869 debug/elf: sync new loong64 relocation types up to LoongArch ELF psABI v20250521
Add several new relocation types defined in newer versions of LoongArch
ELF psABI v20250521, part of the v2.40 spec bundle. The new relocations
are seeing increased adoption because distributions are moving to newer
GNU/LLVM toolchain versions, so Go's internal linker must be prepared to
handle some of them, especially R_LARCH_CALL36 because the ecosystem is
slowly migrating to the "medium" code model by default.

The constants R_LARCH_DELETE and R_LARCH_CFA were removed in LoongArch
ELF psABI v20231102 (spec bundle v2.20), but they are already part of
the public API, so they are retained for now for upholding the go1
compatibility guarantee.

Corresponding binutils implementation:

* R_LARCH_CALL36: https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=dc5f359ed6a36d2c895d89c3e4886f3a2b6d9232

1e433915ce cmd/link,debug/elf: mark Go binaries with no branch target CFI on openbsd
OpenBSD enables Indirect Branch Tracking (IBT) on amd64 and Branch Target
Identification (BTI) on arm64, where hardware permits. Since Go generated
binaries do not currently support IBT or BTI, temporarily mark them with
PT_OPENBSD_NOBTCFI which prevents branch target CFI from being enforced
on execution. This should be removed as soon asn IBT and BTI support are
available.
