tcg/arm: Use r6 as TCG_AREG0 to avoid clash with Thumb framepointer

Browse Source 
On ARM, in Thumb mode r7 is used for the framepointer; this meant
that we would fail to compile in debug mode because we were using r7
for TCG_AREG0. Shift to r6 instead to avoid this clash.
(Bug reported as LP:870990.)
