[WebAssembly] Generalize section ordering constraints Summary: Changes from using a total ordering of known sections to using a dependency graph approach. This allows our tools to accept and process binaries that are compliant with the spec and tool conventions that would have been previously rejected. It also means our own tools can do less work to enforce an artificially imposed ordering. Using a general mechanism means fewer special cases and exceptions in the ordering logic.

# RUN: yaml2obj %s | llvm-objdump -s - | FileCheck %s
# This is a regression test for an issue with the section order
# checker being overly strict. yaml2obj places the relocations last,
# but the section order checker previously checked that relocations
# came before the producers section, which would cause this test to
# fail.

[WebAssembly] Allow multivalue signatures in object files Summary: Also changes the wasm YAML format to reflect the possibility of having multiple return types and to put the returns after the params for consistency with the binary encoding.

[WebAssembly] Rename WasmLimits::Initial to ::Minimum. NFC. This patch renames the "Initial" member of WasmLimits to the name used in the spec, "Minimum". In the core WebAssembly specification, the Limits data type has one required "min" member and one optional "max" member, indicating the minimum required size of the corresponding table or memory, and the maximum size, if any. Although the WebAssembly spec does instantiate locally-defined tables and memories with the initial size being equal to the minimum size, it can't impose such a requirement for imports. It doesn't make sense to require an initial size for a memory import, for example. The compiler can only sensibly express the minimum and maximum sizes. See https://github.com/WebAssembly/js-types/blob/master/proposals/js-types/Overview.md#naming-of-size-limits for a related discussion that agrees that the right name of "initial" is "minimum" when querying the type of a table or memory from JavaScript. (Of course it still makes sense for JS to speak in terms of an initial size when it explicitly instantiates memories and tables.) Differential Revision: https://reviews.llvm.org/D99186
