Subject: [PATCH] fixes #18367 and #21222; using quote inside static block
 (#25907)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

fixes #18367
fixes #21222


1. In vmdef.nim:304, newCtx now sets templInstCounter: new int when it
builds TCtx.
2. vm.nim:1490 — During VM execution of templates, c.templInstCounter is
passed to evalTemplate
3. evaltempl.nim:204 — instID: instID[] dereferences the ref int
4. With a nil templInstCounter, this would crash
5. The same initialization already exists on the semantic side in
sem.nim:787, so this change makes the VM path consistent with the rest
of the compiler.
