llvm-lto support for generating combined function indexes Summary: This patch adds support to llvm-lto that mirrors the support added by r249270 to the gold plugin. This enables better testing of combined index generation for ThinLTO. Added a new test, and this support will be used in the test in D13515.

; Test combined function index generation for ThinLTO via llvm-lto.
Move summary creation out of llvm-as into opt Summary: Let keep llvm-as "dumb": it converts textual IR to bitcode. This commit removes the dependency from llvm-as to libLLVMAnalysis. We'll add back summary in llvm-as if we get to a textual representation for it at some point. In the meantime, opt seems like a better place for that.

[ThinLTO] Support for reference graph in per-module and combined summary. Summary: This patch adds support for including a full reference graph including call graph edges and other GV references in the summary. The reference graph edges can be used to make importing decisions without materializing any source modules, can be used in the plugin to make file staging decisions for distributed build systems, and is expected to have other uses. The call graph edges are recorded in each function summary in the bitcode via a list of <CalleeValueIds, StaticCount> tuples when no PGO data exists, or <CalleeValueId, StaticCount, ProfileCount> pairs when there is PGO, where the ValueId can be mapped to the function GUID via the ValueSymbolTable. In the function index in memory, the call graph edges reference the target via the CalleeGUID instead of the CalleeValueId. The reference graph edges are recorded in each summary record with a list of referenced value IDs, which can be mapped to value GUID via the ValueSymbolTable. Addtionally, a new summary record type is added to record references from global variable initializers. A number of bitcode records and data structures have been renamed to reflect the newly expanded scope of the summary beyond functions. More cleanup will follow.

[ThinLTO] Use valueid instead of bitcode offsets in combined index file Summary: With the removal of support for lazy parsing of combined index summary records (e.g. r267344), we no longer need to include the summary record bitcode offset in the VST entries for definitions. Change the combined index format to be similar to the per-module index format in using value ids to cross-reference from the summary record to the VST entry (rather than the summary record bitcode offset to cross-reference in the other direction). The visible changes are: 1) Add the value id to the combined summary records 2) Remove the summary offset from the combined VST records, which has the following effects: - No longer need the VST_CODE_COMBINED_GVDEFENTRY record, as all combined index VST entries now only contain the value id and corresponding GUID. - No longer have duplicate VST entries in the case where there are multiple definitions of a symbol (e.g. weak/linkonce), as they all have the same value id and GUID. An implication of #2 above is that in order to hook up an alias to the correct aliasee based on the value id of the aliasee recorded in the combined index alias record, we need to scan the entries in the index for that GUID to find the one from the same module (i.e. the case where there are multiple entries for the aliasee). But the reader no longer has to maintain a special map to hook up the alias/aliasee.
