[Asan] Fix __asan_update_allocation_context

Update both thread and stack.
Update thread and stack as atomic operation.
Keep all 32bit of TID as now we have enough bits.

Depends on D87135.

[EarlyCSE] Fix and recommit the revised c9826829d74e637163fdb0351870b8204e62d6e6

In addition to calculate hash consistently by swapping SELECT's
operands, we also need to inverse the select pattern favor to match the
original logic.

[EarlyCSE] Equivalent SELECTs should hash equally

DenseMap<SimpleValue> assumes that, if its isEqual method returns true
for two elements, then its getHashValue method must return the same value
for them. This invariant is broken when one SELECT node is a min/max
operation, and the other can be transformed into an equivalent min/max by
inverting its predicate and swapping its operands. This patch fixes an
assertion failure that would occur intermittently while compiling the
following IR:

    define i32 @t(i32 %i) {
      %cmp = icmp sle i32 0, %i
      %twin1 = select i1 %cmp, i32 %i, i32 0
      %cmpinv = icmp sgt i32 0, %i
      %twin2 = select i1 %cmpinv,  i32 0, i32 %i
      %sink = add i32 %twin1, %twin2
      ret i32 %sink
    }
