[PULL 06/17] target/ppc: Merge fsqrt and fsqrts helpers


From: Daniel Henrique Barboza
Subject: [PULL 06/17] target/ppc: Merge fsqrt and fsqrts helpers
Date: Tue, 20 Sep 2022 16:41:51 -0300

From: Víctor Colombo <victor.colombo@eldorado.org.br>

These two helpers are almost identical, differing only by the softfloat
operation it calls. Merge them into one using a macro.
Also, take this opportunity to capitalize the helper name as we moved
the instruction to decodetree in a previous patch.
