Targets should implement this method to assign a section to globals with an explicit section specfied. The implementation of this method can assume that GV->hasSection() is true.

Implements llvm::TargetLoweringObjectFile.

Given a constant with the SectionKind, return a section that it should be placed in.

getSectionForConstant - Given a mergeable constant with the specified size and relocation information, return a section that it should be placed in.
