Pierrick Bouvier 923710b6d5 plugins: enable linking with clang/lld 
Windows uses a special mechanism to enable plugins to work (DLL delay
loading). Option for lld is different than ld.

MSYS2 clang based environment use lld by default, so restricting to this
config on Windows is safe, and will avoid false bug reports.

Pierrick Bouvier 8f5a4cfc7e win32: remove usage of attribute gcc_struct 
This attribute is not recognized by clang.

An investigation has been performed to ensure this attribute has no
effect on layout of structures we use in QEMU [1], so it's safe to
remove now.

In the future, we'll forbid introducing new bitfields in packed struct,
as they are the one potentially impacted by this change.

Alex Bennée 27f347e6a1 accel/tcg: also suppress asynchronous IRQs for cpu_io_recompile 
While it would be technically correct to allow an IRQ to happen (as
the offending instruction never really completed) it messes up
instrumentation. We already take care to only use memory
instrumentation on the block, we should also suppress IRQs.

Alex Bennée c0e6b8b798 system: propagate Error to gdbserver_start (and other device setups) 
This started as a clean-up to properly pass a Error handler to the
gdbserver_start so we could do the right thing for command line and
HMP invocations.

Now that we have cleaned up foreach_device_config_or_exit() in earlier
patches we can further simplify by it by passing &error_fatal instead
of checking the return value. Having a return value is still useful
for HMP though so tweak the return to use a simple bool instead.
