[InstCombine] Fold "x ?% y ==/!= 0" to "x & (y-1) ==/!= 0" iff y is power-of-two
Summary:
I have stumbled into this by accident while preparing to extend backend `x s% C ==/!= 0` handling.
While we did happen to handle this fold in most of the cases,
the folding is indirect - we fold `x u% y` to `x & (y-1)` (iff `y` is power-of-two),
or first turn `x s% -y` to `x u% y`; that does handle most of the cases.
But we can't turn `x s% INT_MIN` to `x u% -INT_MIN`,
and thus we end up being stuck with `(x s% INT_MIN) == 0`.
There is no such restriction for the more general fold:
https://rise4fun.com/Alive/IIeS
To be noted, the fold does not enforce that `y` is a constant,
so it may indeed increase instruction count.
This is consistent with what `x u% y`->`x & (y-1)` already does.
I think it makes sense, it's at most one (simple) extra instruction,
while `rem`ainder is really much more un-simple (and likely **very** costly).

Summary:
Tab completing inside the multiline expression command can cause LLDB to crash. The easiest way
to do this is to go inside a frame with at least one local variable and then try to complete:
(lldb) expr
1. a[tab]
Reason for this was some mixup when we calculate the cursor position. Obviously we should calculate
the offset inside the string by doing 'end - start', but we are doing 'start - end' (which causes the offset to
become -1 which will lead to some out-of-bounds reading).

There's one caveat: gcc defines _LARGEFILE_SOURCE and _LARGEFILE64_SOURCE for C++ only, while clang has long been doing it for

declarations of fseek/ftello (_LARGEFILE_SOURCE) resp. the 64-bit versions
of largefile functions (*64 with _LARGEFILE64_SOURCE) visible additionally.
However, _FILE_OFFSET_BITS=64 changes all affected functions to be largefile-aware.
I'd like to restrict this to C++, just like gcc does.
To avoid a similar inconsistence with host compilers that don't predefine _FILE_OFFSET_BITS=64

[DivRemPairs] Handling for expanded-form rem - recomposition (PR42673)
Summary:
While `-div-rem-pairs` pass can decompose rem in div+rem pair when div-rem pair
is unsupported by target, nothing performs the opposite fold.
We can't do that in InstCombine or DAGCombine since neither of those has access to TTI.
So it makes most sense to teach `-div-rem-pairs` about it.
If we matched rem in expanded form, we know we will be able to place div-rem pair
next to each other so we won't regress the situation.
Also, we shouldn't decompose rem if we matched already-decomposed form.
This is surprisingly straight-forward otherwise.
