Fix clang/test/Sema/code_align.c for Arm v7 #70762

This patch disables parts of clang/test/Sema/code_align.c that need
__int128_t to be defined. This will fix failures on Arm v7 buildbots
due to #70762

Following bots are failing:
https://lab.llvm.org/buildbot/#/builders/245
https://lab.llvm.org/buildbot/#/builders/178
https://lab.llvm.org/buildbot/#/builders/182
