target/arm: remove run-time semihosting checks for linux-user
Now we do all our checking at translate time we can make cpu_loop a little bit simpler. We also introduce a simple linux-user semihosting test case to defend the functionality. The out-of-tree softmmu based semihosting tests are still more comprehensive.
