For example:
val c = C("...")
val x = c.x // alias to variable for c.x, which depends on c
if (x == null) return
// now c.x has type Any
c = C(null)
// c has been reassigned => info for c.x is no longer valid;
// c itself has never had any statements made about it, but
// we must still call removeAllAboutVariable to clear the
// dependents

All redundant I managed to find, of course.
Why: I'm going to process all reflect dependencies in the next commits.
Cleanup reflect dependency before processing.
They are redundant because:
1. if `compileOnly` then compilation didn't break after dropping the
dependency
2. if `test*` then tests didn't break after dropping the dependency.
3. `analysis/analysis-api-fir/analysis-api-fir-generator/build.gradle.kts`
`compiler/fir/checkers/checkers-component-generator/build.gradle.kts`
Drop `implementation(project(":kotlin-reflect-api"))` because the
module already depends on
`implementation(project(":kotlin-reflect"))`
4. `compiler/daemon/daemon-client/build.gradle.kts`. Drop `runtimeOnly`
because after dropping `compileOnly` compilation didn't break (so
`runtimeOnly` looks suspicious). Less safe than 1-3
Make smart-casts non-transparent expression without delegation
to underlying FirQualifiedAccessExpression, as children delegation in
fir tree has unclear semantics
Remove two different kinds of tree nodes for smart-casts
Consider a function `run2` that has 2 lambda arguments called in place.
We don't know the order in which they're called, so here:
var x: Any? = something
run2(
{ x = null },
{ x as String },
)
// <--
it's not correct to simply `&&` the statements together, as that would
produce `x is Nothing? && x is String && x is Any?`. Instead, statements
should be grouped by assignment first, and different groups are `||`-ed.
This means in the above example we now get `x is Nothing? || (x is Any?
&& x is String)` == `x is String?`.
For example:
foo(
// `if` joins A & B
if (condition)
run { ... } // A
else
run { ... }, // B
run { ... } // C
) // `foo` unifies `A & B` and `C`, so if it is not resolved itself,
// further `if`s, `when`s, safe calls outside it, etc. continue
// building the correct type predicate until the next completed
// call.
