Use LOAD_PIC_REG in i386 atanh [committed]

[Joseph Myers]

sysdeps/i386/fpu/e_atanh.S, unlike all other functions in that
directory, loads the PIC register with its own code using
_GLOBAL_OFFSET_TABLE_, rather than with the LOAD_PIC_REG macro.  I see
no good reason for the difference; this patch makes it use the common
macro.

Tested for x86.  Committed.
