Chris Lattner 9491dee24e Enhance SRoA to be more aggressive about scalarization of aggregate allocas ... that have PHI or select uses of their element pointers. This can often happen when instcombine sinks two loads into a successor, inserting a phi or select. With this patch, we can scalarize the alloca, but the pinned elements are not yet promoted. This is still a win for large aggregates where only one element is used. This fixes rdar://8904039 and part of rdar://7339113 (poor codegen on stringswitch). llvm-svn: 124070		2011-01-23 08:27:54 +00:00
