[aarch64] Adjust Falkor's sign extend reg+reg address cost
Adjust Falkor's register_sextend cost from 4 to 3. This fixes a testsuite
failure in gcc.target/aarch64/extend.c:ldr_sxtw where GCC was generating
a sbfiz instruction rather than a load with sign extension.
No performance changes.

* config/aarch64/aarch64.c (qdf24xx_addrcost_table)
