Fiona Ebner e752bbe5e2 cherry-pick TCG-related stable fixes for 7.2
When turning off the "KVM hardware virtualization" checkbox in Proxmox
VE, the TCG accelerator is used, so these fixes are relevant then.

The first patch is included to allow cherry-picking the others without
changes.

Subject: [PATCH] tests/tcg/i386: Introduce and use reg_t consistently
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Define reg_t based on the actual register width.
Define the inlines using that type. This will allow
input registers to 32-bit insns to be set to 64-bit
values on x86-64, which allows testing various edge cases.
