[AArch64][SVE] Add lowering for rounding operations

[Asif]

Summary

Add the functionality to lower SVE rounding operations for passthru variant.
Created a new test case file for all rounding operations.

1424–1425

So we can prove the DAGCombine for these intrinsics is the canonical route, can you please change this and the following sve_frint instances to null_frag. Once FRECPX and FSQRT follow a similar path we'll remove the parameter.

Since there's no expected variance for these tests can you use update_llc_test_checks.py to generate the check lines. It'll just make it easier in the future if somebody adds anything new.

[paulwalker-arm]

Other than adding the missing test before landing that patch, this LGTM.

It looks like you are missing a test for define <vscale x 2 x double> @frintm_nxv2f64.

Added the missing test.
