  exec: Save CPUState::exception_index field

This patch adds a subsection with exception_index field to the VMState for
correct saving the CPU state.
Without this patch, simulator could miss the pending exception in the saved
virtual machine state.

  -----------
  target-i386: Support migratable=no properly

When the "migratable" property was implemented, the behavior was tested
by changing the default on the code, but actually using the option on
the command-line (e.g. "-cpu host,migratable=false") doesn't work as
expected. This is a regression for a common use case of "-cpu host",
which is to enable features that are supported by the host CPU + kernel
before feature-specific code is added to QEMU.

Fix this by initializing the feature words for "-cpu host" on
x86_cpu_parse_featurestr(), right after parsing the CPU options.

  target-i386: Reject invalid CPU feature names on the command-line

Instead of simply printing a warning, report an error when invalid CPU
options are provided on the CPU model string.
