x86/fpu: Uninline the irq_ts_save()/restore() functions
Especially the irq_ts_save() function is pretty bloaty, generating
over a dozen instructions, so uninline them.
Even though the API is used rarely, the space savings are measurable:
text data bss dec hex filename
13331995 2572920 1634304 17539219 10ba093 vmlinux.before
13331739 2572920 1634304 17538963 10b9f93 vmlinux.after
( This also allows the removal of an include file inclusion from fpu/api.h,
speeding up the kernel build slightly. )
