2013-03-29	PNaCl: Fix ExpandTls to handle a couple of corner cases involving PHI nodes	Mark Seaborn
	ExpandTls's use of replaceUsesOfWith() didn't work for PHI nodes containing the same Constant twice (which needs to work for same or differing incoming BasicBlocks). The same applies to ExpandTlsConstantExpr. I noticed this while implementing ExpandConstantExpr. Fix this and factor out some common code that all three passes can use.

2012-11-29	PNaCl: Add ExpandTls pass for expanding out static TLS variables	Mark Seaborn
	This replaces each reference to a TLS variable "foo" with the LLVM IR equivalent of the expression: ((struct tls_template ) __nacl_read_tp())->foo This pass fills out the global variables __tls_template_start, __tls_template_end etc. which are used by src/untrusted/nacl/tls.c. These are the symbols that are otherwise defined by a binutils linker script. In order to handle the case of TLS variables that occur inside ConstantExprs, we have a helper pass, ExpandTlsConstantExpr.
