This reverts commit 1954436fe28557dab8381f5b0f8ca7d68ab091c8. Reason for revert: The shaderc side of this multi-patch brings in a dependency on glslang, which uses a static initializer, which chromium doesn't like. Original change's description: > Convert spvc build flag to a runtime toggle > > Also moves some of the spirv_cross code into the main library that was > feature guarded, since spvc requires it. > > BUG=dawn:281 > > Change-Id: I482d1d5a5c851956d3815bad90665c52a1ea15bb > Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/13860 > Reviewed-by: Corentin Wallez <cwallez@chromium.org> TBR=cwallez@chromium.org,kainino@chromium.org,enga@chromium.org,rharrison@chromium.org Change-Id: Ia9a025fb4440c96874d1b45776a9f97023ca591d No-Presubmit: true No-Tree-Checks: true No-Try: true Bug: dawn:281 Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/13941 Reviewed-by: Ryan Harrison <rharrison@chromium.org> Commit-Queue: Ryan Harrison <rharrison@chromium.org>
