Replace raw-register AMO asm with proper inline-asm constraints for all three operands (rd, rs2, rs1). Use long long for .d-word AMO variants with pre-set values (xd=0xCAFEBABECAFEBABE, val=0xDEADBEEFDEADBEEF) to avoid uninitialized-data issues. Restore csr_pseudo_main printf output and re-enable amo_main() in the test (was commented out as 'crash on qemu'). Use GEN = $(GEN-TCC) since GCC and TCC produce different fcsr initial values on riscv64.
