s390/vx: add vx-insn.h wrapper include file
The vector instruction macros can also be used in inline assemblies. For this the magic asm(".include \"asm/vx-insn.h\"\n"); must be added to C files in order to avoid that the pre-processor eliminates the __ASSEMBLY__ guarded macros. This however comes with the problem that changes to asm/vx-insn.h do not cause a recompile of C files which have only this magic statement instead of a proper include statement. This can be observed with the arch/s390/kernel/fpu.c file. In order to fix this problem and also to avoid that the include must be specified twice, add a wrapper include header file which will do all necessary steps. This way only the vx-insn.h header file needs to be included and changes to the new vx-insn-asm.h header file cause a recompile of all dependent files like it should.
