Roman Lebedev 0aef747b84 [NFC][X86][Codegen] Megacommit: mass-regenerate all check lines that were already autogenerated 
The motivation is that the update script has at least two deviations
(`<...>@GOT`/`<...>@PLT`/ and not hiding pointer arithmetics) from
what pretty much all the checklines were generated with,
and most of the tests are still not updated, so each time one of the
non-up-to-date tests is updated to see the effect of the code change,
there is a lot of noise. Instead of having to deal with that each
time, let's just deal with everything at once.

This has been done via:
```
cd llvm-project/llvm/test/CodeGen/X86
grep -rl "; NOTE: Assertions have been autogenerated by utils/update_llc_test_checks.py" | xargs -L1 <...>/llvm-project/llvm/utils/update_llc_test_checks.py --llc-binary <...>/llvm-project/build/bin/llc
```

Not all tests were regenerated, however.

; The register+memory form of the BT instruction should be usable on
; pentium4, however it is currently disabled due to the register+memory
; form having different semantics than the register+register form.
; Test these patterns:
; (X & (1 << N)) != 0 --> BT(X, N).
; ((X >>u N) & 1) != 0 --> BT(X, N).
; as well as several variations:
; - The second form can use an arithmetic shift.
; - Either form can use == instead of !=.
; - Either form can compare with an operand of the &
; instead of with 0.
; - The comparison can be commuted (only cases where neither
; operand is constant are included).
; - The and can be commuted.
