Define HAVE_ELF_CORE_DUMP and target_elf_gregset_t in target_elf.h, mirroring the kernel's elf_gregset_t (ELF_NGREG = 66): r0-r31 [0..31], f0-f31 [32..63], pc [64], unique [65]. Implement elf_core_copy_regs() in elfload.c to populate the gregset from CPUAlphaState. Without this, bprm->core_dump is NULL for Alpha targets. When a guest signal goes unhandled, dump_core_and_abort() skips the core write and falls through to die_with_signal(), which re-raises the signal to the host. The host kernel then writes an x86-64 core file for the qemu-alpha process instead of an Alpha guest core. v2: Store thread unique field, same as in Linux kernel.
