JDK-8239931 - [win][x86] vtable stub generation: assert failure (code size estimate) follow-up
Description
When running a {slow | fast}dbg vm with -XX:+DebugVtables, we may crash in VtableStubs::create_vtable_stub() due to a too small size estimate for the generated VM call. 

Solution: adjust size estimates for both x86_64 and x86_32 generators.
Comments
Fix request (13u): The change applies cleanly, tested with tier1, tier2 tests.

Fix Request (JDK 14.0.2) This patch fixes an assertion when debugging vtables and has already been backported to JDK 11u. The fix is low risk and applies cleanly to JDK 14.0.2. In addition to CI testing through all tiers in JDK 15 and 11u, additional testing will be executed in JDK 14.0.2 before pushing.

Fix request (11u): The issue also exists in JDK11. We see the assertion when working with trace code related to vtable stubs. Patch applies cleanly.
