- Introduce new language feature 'ReadDeserializedContracts', which
allows to deserialize contracts from metadata.
- Introduce new language feature 'AllowContractsForCustomFunctions',
which allows reading contracts from sources.
- Use new features instead of combination 'CallsInPlaceEffect ||
ReturnsEffect'
- Rename 'CallsInPlaceEffect' -> 'UseCallsInPlaceEffect',
'ReturnsEffect' -> 'UseReturnsEffect'. As names suggest, they control
if it is allowed to use corresponding effect in analysis.
We have to introduce separate 'ReadDeserializedContracts' to enable
contracts only in some modules of the project, because libraries are
read with project-wide settings (see KT-20692).
Otherwise accessors for backing fields (as in '{ field }') clash with
accessors for properties (as in '{ prop }').

Remove unnecessary non-null parameter checks inside static delegate methods
created for @JvmStatic companion object methods. Allows function generation
strategy decide if such checks need to be injected.

If the loop end value is a compile-time constant (best we can do now),
and it is safe to iterate over a given range using "naive" for loop
(using '<=' or '>=' in loop condition),
generate such loops for Longs and Chars as well Ints (Bytes, Shorts).
In Kotlin 1.3+, assignment to the for-in-array loop range variable in
the loop body doesn't affect loop execution (as if it was a loop on an
array iterator, or some other container).

When the enum entry requires a specific class, its constructor should
invoke proper supertype constructor (from the corresponding enum class).
Corresponding resolved call should be passed from the front-end in
CONSTRUCTOR_RESOLVED_DELEGATION_CALL slice.
In case of enum entries without explicit supertype initializer, this
information was missing.
For-in-string loop can be generated using specialized 'length' and
'charAt' method calls, and with cached string length.
Note that update of the string variable in loop body doesn't affect
loop execution semantics.
#KT-21322 Fixed Target versions 1.2.20
If the range expression is not a local variable (which can be updated in
the loop body affecting loop behavior, see KT-21354), we can cache the
array length, thus turning a for-in-array loop into a simple optimizable
counter loop.
