Pull compiler version requirement update from Arnd Bergmann:
"Require gcc-8 and binutils-2.30

x86 already uses gcc-8 as the minimum version, this changes all other
architectures to the same version. gcc-8 is used is Debian 10 and Red
Hat Enterprise Linux 8, both of which are still supported, and
binutils 2.30 is the oldest corresponding version on those.

Ubuntu Pro 18.04 and SUSE Linux Enterprise Server 15 both use gcc-7 as
the system compiler but additionally include toolchains that remain
supported.

With the new minimum toolchain versions, a number of workarounds for
older versions can be dropped, in particular on x86_64 and arm64.
Importantly, the updated compiler version allows removing two of the
five remaining gcc plugins, as support for sancov and structeak
features is already included in modern compiler versions.

I tried collecting the known changes that are possible based on the
new toolchain version, but expect that more cleanups will be possible.

Since this touches multiple architectures, I merged the patches
through the asm-generic tree."

Kbuild: remove structleak gcc plugin

gcc-12 and higher support the -ftrivial-auto-var-init= flag, after
gcc-8 is the minimum version, this is half of the supported ones, and
the vast majority of the versions that users are actually likely to
have, so it seems like a good time to stop having the fallback
plugin implementation

Older toolchains are still able to build kernels normally without
this plugin, but won't be able to use variable initialization..

kunit/stackinit: Use fill byte different from Clang i386 pattern

The byte initialization values used with -ftrivial-auto-var-init=pattern
(CONFIG_INIT_STACK_ALL_PATTERN=y) depends on the compiler, architecture,
and byte position relative to struct member types. On i386 with Clang,
this includes the 0xFF value, which means it looks like nothing changes
between the leaf byte filling pass and the expected "stack wiping"
pass of the stackinit test.

Use the byte fill value of 0x99 instead, fixing the test for i386 Clang
builds.
