This finishes going through the dev_compiler HTML tests and switches
out unittest for minitest wherever possible.
In the process, it gets another 10 tests strong mode clean, and gets
several more passing, and more not skipped. With this CL, we're running
another 50 more HTML tests (though some are expected to fail, mostly
because of #27578).

When running with --load-deferred-eagerly, we don't need to collect
functions for invalidation, but instead insert runtime checks if
the prefix if loadLibrary was called loaded or not.

Unoptimized code has a static call to optimized code.
Optimized code prologue goes to the OptimizeInvokedFunction runtime.
Callee schedule for background compilation and current code set the return entries return value.
Verify-on-transition triggers a safepoint, wherein the background compiler disables the old optimized code.
The OptimizedInvokedFunction stub calls through the disabled code.
FixCallersTarget see an unoptimized caller. BOOM
Similar problem without --verify-on-transition, except the safepoint comes from BackgroundCompiler::CompileOptimized.
Fixes#26927.

Revert changes to virtual_memory_win.cc in case they are the cause of
the OOM failures on the debug windows x64 bot.

For blobs, put all four pieces into a single file with a header describing their offsets.
For dynamic libraries, move the vm isolate and isolate pieces into the dynamic library as additional read-only sections.
Automatically detect if the script argument is an app snapshot and initialize the VM appropriately, similar to automatic detection of script snapshots.

When loading a snapshot all library prefixes should be considered not
loaded. This makes code running from a JIT snapshot throw the correct
error when using a deferred prefix before it is loaded.
Also, update test status and avoid skipping tests.

Previously, DeclarationResolver matched declarations to elements using their offsets in the file. This meant that it could not work with element models built from a summary, since those element models are not guaranteed to contain offsets. Now, DeclarationResolver assumes that elements appear in the same order in the element model as they do in the file, so it can just match them up using their order.
DeclarationResolver continues to verify element names as it does its matching, so if the ordering of elements ever fails to match up with the ordering of declarations, an exception is almost certain to be thrown. (The only time it wouldn't be is if the mismatch can't be detected due to multiple elements having the same name).
The new implementation is ~1.6x faster than the previous one.

The catch entry block has all locals in fixed locations
(Rj) where j = kNumberOfRegisters - i for parameter i.
This means we reserve a range of DBC registers at the top-end of the frame.
Those registers are blocked for general allocation to avoid any overlap
with the rest of the registers that are allocated from the bottom.
Each optimized frame with a try-catch will be kNumberOfRegisters wide.
