lib: Use __ASSEMBLER__ instead of __ASSEMBLY__

Convert all non-x86 #ifdefs from __ASSEMBLY__ to __ASSEMBLER__, and remove
all manual __ASSEMBLY__ #defines. __ASSEMBLY_ was inherited blindly from
the Linux kernel, and must be manually defined, e.g. through build rules
or with the aforementioned explicit #defines in assembly code.

__ASSEMBLER__ on the other hand is automatically defined by the compiler
when preprocessing assembly, i.e. doesn't require manually #defines for
the code to function correctly.

Ignore x86, as x86 doesn't actually rely on __ASSEMBLY__ at the moment,
and is undergoing a parallel cleanup.

arm: Add test for FPU/SIMD context save/restore

Test that the FPU/SIMD registers are saved and restored correctly when
context switching CPUs.

In order to test fpu/simd functionality, we need to make sure that
kvm-unit-tests doesn't generate code that uses the fpu registers, as that
might interfere with the test results. Thus make sure we compile the tests
with -mgeneral-regs-only.

arm64: Define name for these bits used in SCTLR_EL1

Currently some fields in SCTLR_EL1 don't define a name and directly used
in the SCTLR_EL1_RES1, that's not good now since these fields have been
functional and have a name.

Delete the SCTLR_EL1_RES1 since these bits are not RES1 if the related
feature has been implemented, it's wired to define these bits as RES1.
So simply delete the SCTLR_EL1_RES1 and unwind its definition to
INIT_SCTLR_MMU_OFF.

According to the ARM DDI 0487J.a, define the name related to these
fields.

arm64: Configure SCTLR_EL1 at boot

Some fields in SCTLR_EL1 are UNKNOWN at reset and the arm64 boot
requirements, as stated by Linux in Documentation/arm64/booting.rst, do not
specify a particular value for all the fields. Do not rely on the good will
of the hypervisor and userspace to set SCTLR_EL1 to a sane value (by their
definition of sane) and set SCTLR_EL1 explicitely before running setup().
This will ensure that all tests are performed with the hardware set up
identically, regardless of the KVM or VMM versions.

lib: arm64: Consolidate register definitions to sysreg.h

Move system register field definitions to sysreg.h, where the opcodes for
system register access are defined, to align ourselves with the Linux
kernel. EL2 support, needed for EFI and nested virtualization testing, will
require additional register and field definions, and having them in the
same place as Linux will make maintenance easier.

Adds the following tests:
- event-counter-config: test event counter configuration
- basic-event-count:
- programs counters #0 and #1 to count 2 required events
(resp. CPU_CYCLES and INST_RETIRED). Counter #0 is preset
to a value close enough to the 32b
overflow limit so that we check the overflow bit is set
after the execution of the asm loop.
- mem-access: counts MEM_ACCESS event on counters #0 and #1
with and without 32-bit overflow.

This patch adds two new macros to support read/write operations of ARMv7
and ARMv8 system registers. As part of the change, xstr() is revised to
support variable arguments. With it, ARMv7 system register can be defined
with __ACCESS_CP15() or __ACCESS_CP15_64() depending if it is 32-bit or
64-bit. get_mpidr() is re-written with new macros.
