  kvmvapic: Fix TB invalidation after instruction patching

Since 0b57e287, cpu_memory_rw_debug already triggers a TB invalidation.
As it doesn't (and cannot) set is_cpu_write_access=1 but "consumes" the
currently executed TB, the tb_invalidate_phys_page_range call from
patch_instruction didn't work anymore.

Fix this by open-coding the required bits to restore the CPU state from
the current TB position before patching and resume execution on the
patched instruction afterward.

  Log Message:
  -----------
  vmware_vga: Add back some info in local state partially reverting aa32b38c

Keep saving display surface parameters at init and using these cached
values instead of getting them when needed. Not sure why this is
needed (maybe due to the interaction with the vga device) but not
doing this broke the Xorg vmware driver at least.

  -----------
  tests/tcg: new test for i386 FPREM and FPREM1

This is setting the stage for a cleanup of FPREM and FPREM1 helpers while being
sure that they behave same as bare metal.

The test constructs operands using combinations of corner cases for the
floating-point bitfields and prints operands, result and FPU status word for
FPREM and FPREM1. The outputs can then be compared between bare metal and QEMU.
The 'run-test-i386-fprem' make target does just that.
