Update call-llvm-intrinsics test for Rust 1.94.0 IR

- Rust 1.94 now passes constants directly to llvm.sqrt.f32 instead of
  storing/loading via the stack.

- Updated the FileCheck pattern to match the new IR:
    // CHECK: call float @llvm.sqrt.f32(float 4.000000e+00)

- Test intent unchanged: still ensures that the intrinsic is emitted
  as a 'call' (not 'invoke').

- Added annotations for CI portability:
    //@ add-minicore
    //@ needs-llvm-components: riscv

Fixes #153271
