[PATCH] MIR Serialization: Initial serialization for the machine operand target flags.

[Alex L]

Hi,

This patch implements the initial serialization of the machine operand
target flags.
This patch extends the 'TargetInstrInfo' class to add two new methods that
help
to provide text based serialization.

This patch also overrides the new methods in the X86 target, and thus it is
only
capable of serializing the target flags for the X86 target. The target
flags for the
other targets will be serialized in follow up commits.

In this patch the target flags use the following syntax:

    target-flags( [ <direct-flag> ])

Example:

   target-flags(x86-got)

This syntax will be expanded and will include bit flags when the target
flags from other
targets will be serialized.

Thanks,
Alex
