[NFC][test][ELF] Check DSO's ifunc2 is in .iplt in aarch64-ifunc-bti.s

This mirror's the PIE's CHECK lines, which were already stricter.

Git commit 4e1dfc1c8ecaccf0e7de350277385296a91e35b3 by Jessica Clarke on 19/07/2026 at 16:16..
[NFC][test][ELF] Improve ppc32-ifunc-nonpreemptible-(no)pic.s

Firstly, the nopic test had an unused HEX check line when it should have
been checking .got.plt, and the pic test was only checking .got2, also
ignoring .got.plt.

Secondly, the indentation for instructions was inconsistent within a
single file.

Thirdly, neither test was actually checking the code for func's IPLT
entry in .glink, only that the symbol existed as a normal function that
wasn't the same as the resolver, and the nopic test wasn't even testing
the full contents of the PLT call stub, which was inconsistent with the
pic test.

Fourthly, the pic test used the same output file for two different
links, which can be confusing when debugging.

Finally, the comment at the start of the pic test's PLT call stub had no
bearing on the immediate in use, instead being the same as the nopic's
one with the 4 subtracted from both sides (presumably trying to account
for the nopic test not having the extra .got2 entry, but neglecting the
fact that it's not using absolute addressing, and even if it were, the
addresses are entirely different).
