If LeverVersion is set to greater than 1 of the current compiler version, metadata became null here org.jetbrains.kotlin.load.kotlin.header.ReadKotlinClassHeaderAnnotationVisitor.createHeader, which leads to NPE during incremental analysis. Using the same incompatible data as fallback prevent it

To prevent OutOfMemoryError from converting the whole string to byte
array, in case the snapshot is very big (see KT-51058).
Also, remove 'framebuf' option from -Xprofile help, since async-profiler
2.0+ has unlimited frame buffer.
* thread that by default joins in the destructor (like C++20 jthread)
* can be given a name

Doing so speeds up psi2ir ~2 times, and thus improves total compiler
performance by about 6-8%.
Unless JVM IR is in the mode where linking via signatures is the only
way (-Xserialize-ir, -Xklib), signatures are actually not needed at all,
SymbolTable can use the frontend representation (descriptors for FE1.0,
and hopefully FIR elements for K2) as hash table keys. The only catch is
that since other backends still need to work with signatures, all the
common IR utilities, such as irTypePredicates.kt, need to work correctly
for IR elements both with signatures and without.
Also, introduce a fallback compiler flag -Xlink-via-signatures, in case
something goes wrong, to be able to troubleshoot and workaround any
issues.

The function findDescriptorBySignature should return null if no such signature has been found
letting the caller to handle this correctly. Fixes https://youtrack.jetbrains.com/issue/KT-50976
Unfortunately, neither descriptors nor Lazy IR have enough information
to correctly deduce a enum's modality as psi2ir does, so to avoid the RTTI generator
generating different vtables in different setups (whether a klib is cached or not),
conservatively consider all enums non-final.
