What's Changed

• Propagate deprecated attribute information on functions to Autocomplete entries by @JohnnyMorganz in #2159
• Add Frontend::clearModules() for selective module removal by @JohnnyMorganz in #2331

Analysis

• Internal refactoring in service of supporting cyclic module dependencies.
• Skip error-ish types when computing properties for autocomplete.
• Fix a regression that would cause us erroneously infer {unknown} for array-tables.

export type Glob = { string }
local function parseGlob(): Glob
    -- Prior, we would incorrectly infer that lua_parts has type `{ unknown }`
    local lua_parts = {}
    table.insert(lua_parts, "")
    table.insert(lua_parts, "")
    return {
        table.concat(lua_parts)
    }
end

• Fix a bug where loops could "cancel out" refinements that happened earlier in the block.

type LightingChanger = { [string]: number, Instances: LightingChanger }
local lightingChangers: { LightingChanger } = nil :: any
local closestChanger: LightingChanger?
if #lightingChangers == 1 then
    closestChanger = lightingChangers[1]
end
if closestChanger == nil then
    return
end
for _, _ in closestChanger do
end

-- Prior, we would claim `closestChanger` was `nil`able here.
local _ = closestChanger.Instances

Runtime

• Fix math.round on negative zero in SSE 4.1 mode.
• Make sure to mark direct access callbacks to cover corner cases.

Native Code Generation

• Sink instructions only used by multiple exit sync blocks into them.
• Fix A64 emitBuiltin in DebugCodegenChaosA64 mode.
• Add an option to output information about register spill and restore events.
• Fix the range of registers marked dead in multi-return builtin fastcalls.
