AArch64: Tune case-values-threshold
Tune the case-values-threshold setting for modern cores. A value of 11 improves
SPECINT2017 by 0.2% and reduces codesize by 0.04%. With -Os use value 8 which
reduces codesize by 0.07%.

* config/aarch64/aarch64.c (aarch64_case_values_threshold):
Change to 8 with -Os, 11 otherwise.
