[AArch64] Introduce AArch64SLSHardeningPass, implementing hardening of RET and BR instructions.
Some processors may speculatively execute the instructions immediately
following RET (returns) and BR (indirect jumps), even though
control flow should change unconditionally at these instructions.
To avoid a potential miss-speculatively executed gadget after these
instructions leaking secrets through side channels, this pass places a
speculation barrier immediately after every RET and BR instruction.
Since these barriers are never on the correct, architectural execution
path, performance overhead of this is expected to be low.
On targets that implement that Armv8.0-SB Speculation Barrier extension,
a single SB instruction is emitted that acts as a speculation barrier.
On other targets, a DSB SYS followed by a ISB is emitted to act as a
speculation barrier.
These speculation barriers are implemented as pseudo instructions to
avoid later passes to analyze them and potentially remove them.
Even though currently LLVM does not produce BRAA/BRAB/BRAAZ/BRABZ
instructions, these are also mitigated by the pass and tested through a
MIR test.
The mitigation is off by default and can be enabled by the
harden-sls-retbr subtarget feature.

This commit only adds the equality constraint where the numeric value

ADT: Fix that APSInt's string constructor claims it requires 5 bits to store a zero
Summary:
When constructing an APSInt from a string, the constructor doesn't correctly
truncate the bit width of the result if the passed in string was "0" (or any
alternative way to express 0 like "-0" or "000"). Instead of 1 (which is the
smallest allowed bit width) it returns an APSInt with a bit width of 5.
The reason is that the constructor checks that it never truncates the result to
the invalid bit width of 0, so when it calculates that storing a "0" doesn't
require any bits it just keeps the original overestimated bit width (which
happens to be 5).
This patch just sets the bit width of the result to 1 if the required bit width
is 0.

This makes -fsanitize=kernel-address emit the correct globals
constructors for the kernel. We had to do the following:
* Disable generation of constructors that rely on linker features such
as dead-global elimination.
* Only instrument globals *not* in explicit sections. The kernel uses
sections for special globals, which we should not touch.
* Do not instrument globals that are prefixed with "__" nor that are
aliased by a symbol that is prefixed with "__". For example, modpost
relies on specially named aliases to find globals and checks their
contents. Unfortunately modpost relies on size stored as ELF debug info
and any padding of globals currently causes the debug info to cause size
reported to be *with* redzone which throws modpost off.

The current logic we have is that we prepare section content in a buffer first and write

and stops writing when the limit is reached and raises the internal error flag.
Later, this flag is is checked before the actual writing to a file happens and
