Add jmp_buf-macros.h

Verify that sizes, alignments and field offsets of jmp_buf as well as
sigjmp_buf are unchanged regardless how struct __jmp_buf_tag is defined.
Since jmp_buf is target specific, jmp_buf-macros.h is added for each
Linux target.  A new target must provides its own jmp_buf-macros.h.

TODO: Hurd needs to provide a jmp_buf-macros.h.

Tested with build-many-glibcs.py.

	* include/setjmp.h [!_ISOMAC]: Include <stddef.h> and
	<jmp_buf-macros.h>.

	[!_ISOMAC] (TEST_OFFSET): Likewise.
	[!_ISOMAC] Add _Static_assert to check sizes, alignments and
	field offsets of jmp_buf as well as sigjmp_buf.
