This patch makes the following System Registers Read Only:
- CurrentEL
- ICH_MISR_EL2
- PMBIDR_EL1
- PMSIDR_EL1
as found in:
https://developer.arm.com/docs/ddi0595/e/aarch64-system-registers
Relative line numbers were also added to the tests so we get more
informative error messages on failure.

This patch resubmits the SVE ZIP1/ZIP2 patch series consisting of
of r320992, r320986, r320973, and r320970 by reverting
https://reviews.llvm.org/rL321024.
The issue that caused r321024 has been addressed in https://reviews.llvm.org/rL321158,
so this patch-series should be safe to resubmit.

This reverts changes r320992, r320986, r320973, and r320970.
r320970 by itself breaks the test case, and the rest depend on it.
Test case will land soon.

The Statistical Profiling Extension is an optional extension to
ARMv8.2-A. Since it is an optional extension, I have added the
FeatureSPE subtarget feature to control it. The assembler-visible parts
of this extension are the new "psb csync" instruction, which is
equivalent to "hint #17", and a number of system registers.
