To allow running Firefox on processors without LASX (for example Loongson 2K3000; note that LSX is guaranteed for LoongArch desktop processors but LASX is not), only use -mlasx on the source files those a runtime check for LASX guards. The runtime check is in SkOpts.cpp and it's enabled after removing -mlasx for this translation unit, if LASX is available at runtime the code in SkOpts_lasx.cpp will be needed to configure Skia to use LASX. Thus we need to add SkOpts_lasx.cpp into the list of sources to build.
