Assembler::AbortedCodeGeneration() is defined in assembler-arm64.h, but it calls
into Constant::Clear() which is defined in assembler-arm64.cc. This introduces
dependency to v8_base component when including assembler-arm64.h which is not
always possible like for V8 unittests target. To fix this, we could define both
in the same file, like Assembler::IsConstPoolEmpty() calls Constant::Clear() and
both are defined in assembler-arm64.h, so it works fine.
