LTO: Hash the set of imported symbols for each module. This set may affect code generation and is sensitive to link order (and possibly in the future to the linker's choice of prevailing symbol), so we need to include it. Differential Revision: https://reviews.llvm.org/D30586 llvm-svn: 296907

; RUN: opt -module-hash -module-summary %s -o %t.bc
; RUN: opt -module-hash -module-summary %S/Inputs/cache-import-lists1.ll -o %t1.bc
; RUN: opt -module-hash -module-summary %S/Inputs/cache-import-lists2.ll -o %t2.bc
; Tests that the hash for t is sensitive to the set of imported functions
; for each module, which in this case depends on the link order (the function
; linkonce_odr will be imported from either t1 or t2, whichever comes first).
; RUN: rm -rf %t.cache
llvm-lto2: Move the LTO::run() action behind a subcommand. Move LTO::run() to a "run" subcommand so that we can introduce new subcommands for testing different parts of the LTO implementation. This doesn't use llvm::cl subcommands because it doesn't appear to be currently possible to pass an argument not associated with a subcommand to a subcommand (e.g. -lto-use-new-pm, -mcpu=yonah).
