controlExpr of GT_CALL node can be contained to enable moving the lower 12-bits of the constant to GT_CALL's instruction (in this case, jalr) offset.

See #114488 for a similar optimization applied to GT_IND and load / store instruction.

For the following C# code:

[MethodImpl(MethodImplOptions.NoInlining)]
private static int MemoryAccess(int[] a, int b)
{
      return a[b];
}

Before patch:

;; ...
lui            a0, 515670
addiw          a0, a0, 786
slli           a0, a0, 13
addi           a0, a0, 2024
slli           a0, a0, 3
jalr           a0           // CORINFO_HELP_RNGCHKFAIL

After patch:

;; ...
lui            a0, -173851
addiw          a0, a0, -1851
slli           a0, a0, 31
srli           a0, a0, 17
jalr           ra, -192(a0)         // CORINFO_HELP_RNGCHKFAIL

Regressions reported here are actually improvements. They are reported as regression because we are able to generate 5 or fewer instruction instead of using emitDataConst, which has fewer instructions (auipc + ld), but actually costs more since it uses ld.
