[TLS] New lower emutls pass, fix linkage bugs. 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

[MC] Use .p2align instead of .align For historic reasons, the behavior of .align differs between targets. Fortunately, there are alternatives, .p2align and .balign, which make the interpretation of the parameter explicit, and which behave consistently across targets. This patch teaches MC to use .p2align instead of .align, so that people reading code for multiple architectures don't have to remember which way each platform does its .align directive.
