Subject: Sink DwarfUnit::constructImportedEntityDIE into DwarfCompileUnit.
X-Git-Url: http://plrg.eecs.uci.edu/git/?p=oota-llvm.git;a=commitdiff_plain;h=ab08da75d70c76fd946483e29366264c92cc092b

Sink DwarfUnit::constructImportedEntityDIE into DwarfCompileUnit.

So that it has access to getOrCreateGlobalVariableDIE. If we ever support
decsribing using directive in C++ classes (thus requiring support in type
units), it will certainly use another mechanism anyway.

Differential Revision: http://reviews.llvm.org/D5975
