[PATCH] D55892: [OpenMP] 'close' map-type-modifier code generation

This patch provides codegen support for close map-type-modifier in map clause.

A map clause with the close map-type-modifier is a hint to prefer that the 
variables are mapped using a copy into faster memory.

[NOTE: This will be committed to trunk after support for close 
map-type-modifier is added in libomptarget. This revision is being created to 
avoid duplication of work by other people.]
