    aarch64: PR target/105157 Increase number of cores TARGET_CPU_DEFAULT c=
an
encode

    This addresses the compile-time increase seen in the PR target/105157. =
This
was
    being caused by selecting the wrong core tuning, as when we added the
latest
    AArch64 the TARGET_CPU_generic tuning was pushed beyond the 0x3f mask we
used
    to encode both target cpu and attributes into TARGET_CPU_DEFAULT.

    gcc/ChangeLog:

            PR target/105157
            * config.gcc: Shift ext_mask by TARGET_CPU_NBITS.
            * config/aarch64/aarch64.h (TARGET_CPU_NBITS): New macro.
            (TARGET_CPU_MASK): Likewise.
            (TARGET_CPU_DEFAULT): Use TARGET_CPU_NBITS.
            * config/aarch64/aarch64.cc (aarch64_get_tune_cpu): Use
TARGET_CPU_MASK.
            (aarch64_get_arch): Likewise.
            (aarch64_override_options): Use TARGET_CPU_NBITS.=
