[gomp-nvptx 3/9] nvptx backend: add two more identifier maps

[Alexander Monakov]

This allows to rewrite libgcc wrappers in C by adding back-maps
__nvptx_real_malloc -> malloc and __nvptx_real_free -> free.  While at it,
I've made the implementation leaner.

        * config/nvptx/nvptx.c (nvptx_name_replacement): Rewrite.  Add
        __nvptx_real_malloc -> malloc and __nvptx_real_free -> free
        replacements.
