[committed] libphobos: Add missing ControlState variable for AArch64

[Iain Buclaw via Gcc-patches]

Hi,

This patch fixes a typo that occurred during the splitting of the
std.math module into a package.

Bootstrapped and regression tested on aarch64-linux-gnu, and committed
to mainline.

Regards,
Iain.
