- Add assert(pred == edge) in fgRemoveRefPred to verify the edge found
  by linear search matches the edge being removed.
- Add early return in fgRedirectEdge when the destination is already
  the target, avoiding unnecessary pred list manipulation and a false
  fgModified signal.

- Fix operator precedence bug: *metric++ increments the pointer instead
  of the value. Changed to (*metric)++ so the metric counter is actually
  bumped when profile data becomes inconsistent.
- Fix wrong InstrumentationKind check in BlockCountInstrumentor::Instrument
  DEBUG path: EdgeIntCount can never match for block counts; changed to
  BasicBlockIntCount so 32-bit counters are written correctly.
- Fix swapped arguments to fgGetPredForBlock in edge instrumentor DEBUG
  path: was searching source's pred list for target (reverse edge) instead
  of target's pred list for source (correct edge).
- Remove dead code: missingEdges variable was initialized to 0 and never
  incremented, making the check always false.
- Fix typos: unsychronized, Don't instrumenting, affeted, bome.

- Fix use-after-free: stack-local BasicBlock bb0 was stored in
  fgIndexToBlockMap and accessed during codegen after the function
  returned. Heap-allocate it from the JIT allocator instead.
- Fix comparator strict weak ordering violation in comesBefore lambda
  used with jitstd::sort: when both intervals are loops with the same
  chain start and end, comesBefore(x, x) returned true, violating
  irreflexivity. Now returns false for equal elements.
- Remove unused 'first' variables in DumpDot() and FindNested() DEBUG
  blocks.
- Fix parameter name mismatch in WasmDfs declaration (ByEH -> ViaEH)
  to match definition and all call sites.
- Fix typos: assingnment, putcode, lookin.

- Fix ReverseLikelihoods: function was a complete no-op. The inner loop
  iterated over successors but never used the loop variable, the
  likelihoods vector was reversed in place but never written back to
  edges. Removed the spurious inner loop and added write-back logic.
- Fix RandomizeLikelihoods: reserve(N) sets capacity but not size,
  making subsequent operator[] access undefined behavior. Changed to
  resize(N, 0) so elements are properly constructed.
- Remove redundant SumOutgoingLikelihoods call in BlendLikelihoods:
  the outer call at line 672 computed sum for every block (including
  no-successor blocks) but the result was unused and shadowed by an
  inner declaration. Moved the call into the BBJ_COND/BBJ_SWITCH case.
- Fix typos: multply, ony.

Fix tree->OperIs(GT_IND) to inlineCandidate->OperIs(GT_IND) in
LateDevirtualization - tree is always GT_RET_EXPR so the check
was dead code. The intent is to check the inline candidate node
for RVA static byref reinterpretation.

Also fix stale comment header (AssignStructInlineeToVar ->
StoreStructInlineeToVar) and typos: obtain -> obtained,
indicies -> indices (3x), ensabled -> enabled,
assetionProp -> assertionProp.

Clarify inThisFlt as alias for inThisHnd (filters use handler index;
the distinction is made by acdKeyDsg). Rename shadowing variable
'map' to 'acdMap' in fgCloneTryRegion to avoid shadowing the outer
BlockToBlockMap. Fix inverted comment about fgCloneFinally direction.
Fix typos: an->and, tested trys->nested tries, lexcially->lexically,
indicies->indices (2x), thge->the.
