[PATCH] Remove m_nloops field from loop_versioning

[Andrew Pinski]

This is a small cleanup of loop_versioning where m_nloops
is only used in the constructor so we can remove the whole
field.

Bootstrapped and tested on x86_64-linux-gnu.

gcc/ChangeLog:

        * gimple-loop-versioning.cc (loop_versioning): Remove m_nloops field.
        (loop_versioning::loop_versioning): Remove initialization of
        m_nloops field and move it to be a local variable.
        (loop_versioning::analyze_blocks): Fix formating.
