Tim Northover 9bdd785014 ARM: diagnose ARM/Thumb assembly switches on CPUs only supporting one.
Some ARM CPUs only support ARM mode (ancient v4 ones, for example) and some
only support Thumb mode (M-class ones currently). This makes sure such CPUs
default to the correct mode and makes the AsmParser diagnose an attempt to
switch modes incorrectly.
