Bradley Smith cf0da91ba5 [AArch64][SVE/NEON] Add support for FROUNDEVEN for both NEON and fixed length SVE 
Previously NEON used a target specific intrinsic for frintn, given that
the FROUNDEVEN ISD node now exists, move over to that instead and add
codegen support for that node for both NEON and fixed length SVE.

Eli Friedman 8dfb5d767e [clang codegen][AArch64] Use llvm.aarch64.neon.fcvtzs/u where it's necessary 
fptosi/fptoui have similar, but not identical, semantics.  In
particular, the behavior on overflow is different.

Fixes https://bugs.llvm.org/show_bug.cgi?id=46844 for 64-bit.  (The
corresponding patch for 32-bit is more involved because the equivalent
intrinsics don't exist, as far as I can tell.)

Luke Geeson dc54b37414 [AArch64] Corrected FP16 Intrinsic range checks in Clang + added Sema tests 
Summary:
This fixes the ranges for the vcvth family of FP16 intrinsics in the clang front end. Previously it was accepting incorrect ranges
-Changed builtin range checking in SemaChecking
-added tests SemaCheck changes - included in  their own file since no similar one exists
-modified existing tests to reflect new ranges
