tcg/arm: Simplify use_armv5t_instructions

Browse Source 
According to the Arm ARM DDI 0406C, section A1.3, the valid variants
are ARMv5T, ARMv5TE, ARMv5TEJ -- there is no ARMv5 without Thumb.
Therefore simplify the test from preprocessor ifdefs to base
architecture revision.  Retain the "t" in the name to minimize churn.
