AARCH64: fail to build variant=core on 11u

Reproducible:
$sh ./configure --with-debug-level=release --with-jvm-variants=core

$ make hotspot CONF=linux-aarch64-normal-core-releas

Analysis:
globals.hpp define InlineSmallCode and it requires dp_InlineSmallCode.

  product_pd(intx, InlineSmallCode, \
          "Only inline already compiled methods if their code size is " \
          "less than this") \
          range(0, max_jint) \
                                                                            \
on aarch64, its defined by in src/hotspot/cpu/aarch64/globals_aarch64.hpp

#if defined(COMPILER1) || defined(COMPILER2)
define_pd_global(intx, InlineSmallCode, 1000);
#endif

variant=core means interpreter-only. Neither COMPILER1 nor COMPILER2 is defined then, so we don't have pd_InlineSmallCode.

JDK-8235673 split InlineSmallCode and other inline-relevant flags to c1_globals.hpp and c2_globals.hpp. I think we need to backport it first to unlock variant=core.
