Should be 68.  Confusion is probably caused by the fact that the note
size is 144, and that the amd64 register set is also 144.  The fact
that the GDB gcore produces wrong core files in the 32x64 case doesn't
help either.

Committed.

	* i386-linux-tdep.c (i386_linux_regset_sections): Size of the
	general-purpose register set should be 68 instead of 144.
	(i386_linux_sse_regset_sections): Likewise.
	(i386_linux_avx_regset_sections): Likewise.
