Previous implementation in http://reviews.llvm.org/D10522 created external references to __emutls_v.* variables. Such references are inaccurate and cannot be handled by all linkers, e.g. Android dynamic and gold linkers for aarch64. Now a new LowerEmuTLS pass to go through all global variables, and add emutls_v.* and emutls_t.* variables. These __emutls* variables have the same linkage and visibility as the associated user defined TLS variable. Also removed old code that dump __emutls* variables in AsmPrinter.cpp, and updated TLS unit tests. Differential Revision: http://reviews.llvm.org/D15300 llvm-svn: 257718
