kbuild,arc: add CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE_O3 for ARC
arch/arc/Makefile overrides -O2 with -O3. This is the only user of ARCH_CFLAGS. There is no user of ARCH_CPPFLAGS or ARCH_AFLAGS. My plan is to remove ARCH_{CPP,A,C}FLAGS after refactoring the ARC Makefile. Currently, ARC has no way to enable -Wmaybe-uninitialized because both -O3 and -Os disable it. Enabling it will be useful for compile-testing. This commit allows allmodconfig (, which defaults to -O2) to enable it. Add CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE_O3=y to all the defconfig files in arch/arc/configs/ in order to keep the current config settings.
