[IR][Verifier] Relax restriction on alloca address spaces In the WebAssembly target, we would like to allow alloca in two address spaces. The alloca instruction already has an address space argument, but the verifier asserts that the address space of an alloca is the default alloca address space from the datalayout. This patch removes this restriction. Targets that would like to impose additional restrictions should do so via target-specific verification passes.

LLParser: add an argument for overriding data layout and do not check alloca addr space Sometimes users do not specify data layout in LLVM assembly and let llc set the data layout by target triple after loading the LLVM assembly. Currently the parser checks alloca address space no matter whether the LLVM assembly contains data layout definition, which causes false alarm since the default data layout does not contain the correct alloca address space. The parser also calls verifier to check debug info and updating invalid debug info. Currently there is no way to let the verifier to check debug info only. If the verifier finds non-debug-info issues the parser will fail. For llc, the fix is to remove the check of alloca addr space in the parser and disable updating debug info, and defer the updating of debug info and verification to be after setting data layout of the IR by target. For other llvm tools, since they do not override data layout by target but instead can override data layout by a command line option, an argument for overriding data layout is added to the parser. In cases where data layout overriding is necessary for the parser, the data layout can be provided by command line. Differential Revision: https://reviews.llvm.org/D41832 llvm-svn: 323826

AllocaInst should store Align instead of MaybeAlign. Along the lines of D77454 and D79968. Unlike loads and stores, the default alignment is getPrefTypeAlign, to match the existing handling in various places, including SelectionDAG and InstCombine.
