[Qemu-devel] [PULL 29/49] target/ppc: remove getVSR()/putVSR() from int_helper.c

[David Gibson]

From: Mark Cave-Ayland <mark.cave-ayl...@ilande.co.uk>

Since commit 8a14d31b00 "target/ppc: switch fpr/vsrl registers so all VSX
registers are in host endian order" functions getVSR() and putVSR() which used
to convert the VSR registers into host endian order are no longer required.

Now that there are now no more users of getVSR()/putVSR() these functions can
be completely removed.
