Roman Lebedev fb4eed381d X86DAGToDAGISel::matchBitExtract() with truncation (PR36419) 
Summary:
Previously in D54095 i have added support for extraction of `lshr` from `X` if we are to produce `BEXTR`.
That was good, but the fix was partial, there was still [[ https://bugs.llvm.org/show_bug.cgi?id=36419 | PR36419 ]].

That pattern can also appear, roughly, when you have a large (64-bit) storage, and the consume bits from it.
It will not be unexpected if you will be doing further computations in 32-bit width.
And then the current code breaks, as the tests show.

The basic idea/pattern here is following:
1. We have `i64` input
2. We perform `i64` right-shift on it.
3. We `trunc`ate that shifted value
4. We do all further work (masking) in `i32`

Since we see `trunc`ation and not `lshr`, we give up, and stop trying to extract that right-shift.
BUT. The mask is `i32`, therefore we can extend both of the operands of the masking (`and`) to `i64`
and truncate the result after masking: https://rise4fun.com/Alive/K4B
```
Name: @bextr64_32_b1 -> @bextr64_32_b0
  %shiftedval = lshr i64 %val, %numskipbits
  %truncshiftedval = trunc i64 %shiftedval to i32
  %widenumlowbits1 = zext i8 %numlowbits to i32
  %notmask1 = shl nsw i32 -1, %widenumlowbits1
  %mask1 = xor i32 %notmask1, -1
  %res = and i32 %truncshiftedval, %mask1
=>
  %shiftedval = lshr i64 %val, %numskipbits
  %widenumlowbits = zext i8 %numlowbits to i64
  %notmask = shl nsw i64 -1, %widenumlowbits
  %mask = xor i64 %notmask, -1
  %wideres = and i64 %shiftedval, %mask
  %res = trunc i64 %wideres to i32
```

Thus, we are again able to extract that `lshr` into `BEXTR`'s control.

Now, the perf (via `llvm-exegesis`) of the snippet suggests that it is not a good idea:
