Bug 1395212 - Update wr::DisplayListBuilder to expose separate APIs for defining and pushing scroll layers. r?mstange This makes the DisplayListBuilder scrolling API more consistent with the clipping API, and allows for more optimization at the call site (in the next patch).

Bug 1395212 - Hoist the scroll layer deduplication code out of bindings.rs into wr::DisplayListBuilder. r?mstange This also splits the wr_dp_push_scroll_layer function in bindings.rs into two separate functions. This makes the API consistent with clipping, and also allows for optimizations in the upcoming patches. MozReview-Commit-ID: IXnOZK0dZm

Bug 1186409 - Use a single global for all JSMs. This patch adds a preference jsloader.shareGlobal that makes it so that JSMs share a single global, in order to reduce memory usage. The pref is disabled by default, and will be enabled in a later bug. Each JSM gets its own NonSyntacticVariablesObject (NSVO), which is used for top level variable bindings and as the value of |this| within the JSM. For the module loader, the main change is setting up the shared global, and the NSVO for each JSM. A number of files are blacklisted from the shared global, because they do things to the global that would interfer with other JSMs. This is detailed in mozJSComponentLoader::ReuseGlobal().

Bug 1230910 Replace GetExceptionCode() with a constant choice of EXCEPTION_ACCESS_VIOLATION. While MinGW appears to define the macro (mapping it to the function _exception_code) there is no definition of the function, so it results in a linker error. MozReview-Commit-ID: E5qZSA2Hsff
