GCC 16 is the first release to include the Algol68 frontend (ga68). Add ga68-g161 pointing to gcc-16.1.0, and set it as the default compiler, with the nightly snapshot remaining for trunk. 🤖 Generated by LLM (Claude, via OpenClaw)
23 cross-compiler architectures: arm, arm-unknown (eabi), arm64, avr, bpf, c6x, hppa, loongarch64, m68k, mips, mips64, mips64el, mipsel, powerpc, powerpc64, powerpc64le, riscv32, riscv64, s390x, sh, sparc, sparc64, sparc-leon. Note: msp430 uses TI-specific distributions, not gcc-cross-builder. No Algol68 cross entries needed — ga68 is a native-only frontend. 🤖 Generated by LLM (Claude, via OpenClaw)

Pull request overview
This PR updates Compiler Explorer’s Amazon properties to add GCC 16.1.0 toolchains (native and cross) across multiple language frontends, and sets GCC 16.1-based entries as defaults where applicable.
Changes:
- Add GCC 16.1 compiler entries (and corresponding “assertions” builds) for multiple languages (C/C++, Ada, Fortran, D, Go, Rust GCC frontend, ObjC/ObjC++).
- Add/extend GCC 16.1 cross-compiler entries for several architectures (notably in the large C/C++ property files).
- Update defaults and some tool paths (e.g., demangler/objdumper/linker) to point at GCC 16.1.0.

Fixes a cosmetic bug introduced in #8642: \`armug1610\` and \`carmug1610\` were missing the \`name\` property, causing both the regular and unknown-eabi ARM GCC 16.1.0 compilers to appear identically as "ARM GCC 16.1.0" in the UI. All other \`armug*\` / \`carmug*\` entries have an explicit \`name=ARM GCC X.Y.Z (unknown-eabi)\` property; this PR adds the same for 16.1.0. *(I'm Molty, an AI assistant acting on behalf of @mattgodbolt)* Co-authored-by: mattgodbolt-molty <mattgodbolt-molty@users.noreply.github.com>

Follow-up to #8642 which added native GCC 16.1.0 and cross C/C++ compilers but missed the Ada and Fortran cross-compiler entries. ## Ada (GNAT) cross compilers added (13 architectures) arm, arm64, hppa, loongarch64, mips, mips64, powerpc, powerpc64, powerpc64le, riscv64, s390x, sparc, sparc64 Note: sparc-leon skipped — `CT_CC_LANG_ADA` is disabled in the 16.1.0 ct-ng config for that target. Arches with Ada disabled in ct-ng (avr, bpf, c6x, m68k, mips64el, mipsel, msp430, riscv32) are also skipped. ## Fortran cross compilers added (17 architectures) arm, arm64, hppa, loongarch64, mips, mips64, mips64el, mipsel, powerpc, powerpc64, powerpc64le, riscv32, riscv64, s390x, sparc, sparc64, sparc-leon refs #7948 *(I'm Molty, an AI assistant acting on behalf of @mattgodbolt)* 🤖 Generated by LLM (Claude, via OpenClaw) Co-authored-by: mattgodbolt-molty <mattgodbolt-molty@users.noreply.github.com>
