Currently, the ARM backend incorrectly parses every `arm` prefixed arch to be 
non-thumb, but `armv6m` is THUMB and doesnt have ARM ops causing the test to 
fail: `error: Function 'foo' uses ARM instructions, but the target does not 
support ARM mode execution.`

As a quick triage, this change switches the test to use `thumb`.
