Before going any further, this updates the existing testcases that really
require -fno-trapping-math to now use that.
It also adds three new tests for SVE. They will however fail until the last
patch but that's fine.
Notable is testcase gcc.target/aarch64/sve/unpacked_cond_frinta_2.c which
without -ftrapping-math (which it's explicitly checking for) generates worse
code because the vectorizer forces an unneeded unpack. This is however the
same issue with how the vectorizer picks VF as we've seen a number of times.
Bootstrapped Regtested on aarch64-none-linux-gnu,
arm-none-linux-gnueabihf, x86_64-pc-linux-gnu
-m32, -m64 and no issues.
Any comments?
Thanks,
Tamar
