Bug 1500926 - Part 3: Remove unused WebIDL Codegen items, r=bzbarsky Differential Revision: https://phabricator.services.mozilla.com/D9465

Bug 1500926 - Part 2: Support a test-only edgecase in Codegen.py, r=bzbarsky When running tests, we can build a WebIDL environment with no interfaces exposed on the primary global. Unfortunately, due to the perfecthash.py logic not handling empty tables, this causes an assertion to be raised. We can work around this by generating some dummy code for that situation, as we will never try to build it. Differential Revision: https://phabricator.services.mozilla.com/D9407

Bug 1500926 - Part 1: Use a statically generated perfect hash in WebIDLGlobalNameHash, r=bzbarsky This strategy allows us to dodge dynamic allocations in WebIDLGlobalNameHash. This removes the Init() and Shutdown() methods, as well as Register. The RegisterBindings.cpp file now only contains static data and one method declaration for the WebIDLGlobalNameHash class. This should also be faster by making the hashtable lookup infallible. Differential Revision: https://phabricator.services.mozilla.com/D9406

Bug 1500927 - Add copy-free jsstring support to perfecthash.py, r=bzbarsky This is needed for bug 1500926. It takes the approach of taking a JSFlatString and using AutoAssertCannotGC to read the memory directly from the JS heap. This lets us avoid re-encoding strings when performing lookups, which can be advantageous. Only ASCII strings are supported by this handler, and wide strings are hashed as though they contain only values under 0x7f. This is OK as invalid keys to perfecthash may return any hashtable entry.

Bug 1453425 - Add test for relative scroll offset updates. r=botond

Bug 1453425 - Add relative scroll offset updates using nsGkAtoms::relative. r=botond This commit adds a scroll origin, nsGkAtoms::relative, which can be used to mark main thread scrolling that can be combined with a concurrent APZ scroll. The behavior of this is controlled by a pref, apz.relative-update. This pref is initially activated and is intended as an aid to narrowing down causes of regressions for users in bug reports. Relative scroll updates work by tracking the last sent or accepted APZ scroll offset. This is sent along with every FrameMetrics. Additionally, a flag is added to FrameMetrics, mIsRelative, indicating whether the scroll offset can be combined with a potential APZ scroll. When this flag is set, AsyncPanZoomController will apply the delta between the sent base scroll offset, and sent new scroll offset. This flag is controlled by the last scroll origin on nsGfxScrollFrame. The new origin, `relative`, is marked as being able to clobber APZ updates, but can only be set if all scrolls since the last repaint request or layers transaction have been relative.

Bug 1453425 - Use ScrollByCSSPixels in relative scrolling DOM API's. r=botond This commit changes `Window::ScrollBy` and `Element::ScrollBy` to use ScrollByCSSPixels in preparation for marking ScrollByCSSPixels as a relative scroll API.

Bug 1453425 - Add RepaintRequest for use of FrameMetrics in repaint requests. r=botond FrameMetrics is currently used in about three ways. 1. Main thread to APZ transactions 2. Storing information in AsyncPanZoomController 3. APZ to main thread repaint requests There's overlap in the use of fields in all these use cases, but it's not perfect. In a following commit, I'd like to change the information used for (1) to support relative scroll offset updates. This information isn't needed for (2) or (3), so it would be good to refactor FrameMetrics out into these use cases. This commit refactors out (3) as it is fairly easy to do. I'd like to refactor (2) out as well, but that is trickier. I'd like to leave that for a future followup. Differential Revision: https://phabricator.services.mozilla.com/D7127

Bug 1492663 - Upgrade most CI builds to clang 7 r=froydnj The cctools-port linker links against libraries from clang (for LTO), which have different SONAMEs depending on the clang version. Which means the linker needs to be used along the same version of clang it was built against. Thus we also make it depend on linux64-clang-7. But changing the dependency is not enough, cf. bug 1471905, so also touch its build script, which it turns out, we need to do anyways because llvm-dsymutil was renamed to dsymutil. Relatedly, all toolchains that are built using cctools-port need to use linux64-clang-7 too. Building compiler-rt 7 with the OSX 10.11 SDK fails because of some newer APIs being used in compiler-rt for xray, but this is not a feature we use, so disable that.
