f03d4a1ffe LibJS/JIT: Resolve the PropertyLookupCache pointers at JIT time
We know where the lookup cache is by the time we're jitting code, so
let's put the pointer directly into the instruction stream.

We can resolve the IdentifierTableIndex to a DeprecatedFlyString& once
when jitting the code, instead of every time GetById executes.

7e3cfaf08c LibJS/JIT: Include headers before they are used
JIT_ARCH_SUPPORTED is defined in LibJIT/Assembler.h, so we need to
include it first.

This change also moves the non-JIT headers outside the #ifdef

bacbd830fe LibJIT: Make X86_64Assembler::native_call take u64 instead of void*
Now that x86-specific Assembler will be compiled on every architecture
we can't rely on void* being the right width.
It also fixes compilation on targets which have void*
be different length from u64 (WASM in particular).

8aa35f4fab LibJIT+LibJS: Rename Assembler to X86_64Assembler
This is in preparation for making LibJIT support multiple architectures.
Assembler will now be typedefed to the specific assembler
for a particular architecture.
Additionally, there's now JIT_ARCH_SUPPORTED which is defined on
architectures which LibJIT supports.

9f5450527f LibJS+LibJIT: Make Assembler::native_call accept preserved_registers
This makes JS::JIT::Compiler less architecture-specific
and unifies aligning the stack into a single operation,
where previously we were doing it separately for preserved registers
and for stack arguments.

58e2fe895c LibJS: Stash thrown exception in a register before executing finalizer
This kills 2 birds with one stone:
1. It makes sure generated check_exception() calls in the finalizer
   don't mis-read the pending exception as caused by their matching
   operation.
2. It implicitly ensures that terminated finally blocks (by a return
   statement) overwrite any pending exceptions, since they will never
   execute the ContinuePendingUnwind operation that restores the
   stashed exception.
This additional logic is required in the JIT (as opposed to the
interpreter), since the JIT uses the exception register to store and
check the possibly-exceptional results from each individual operation,
while the interpreter only modifies it when an operation has thrown an
exception.

aaa81cd3b9 Revert "LibJS/JIT: Clear exception before executing finalizer"
This reverts commit 0daebef727.

Finally blocks do not unconditionally swallow pending exceptions.
This resolves #21759 and fixes the 2 remaining failing test-js tests.

e400682fb1 LibJS/JIT: Support alternative entry point blocks
If Interpreter::run_and_return_frame is called with a specific entry
point we now map that to a native instruction address, which the JIT
code jumps to after the function prologue.

68f4d21de2 LibJS: Lazily collect stack trace information
The previous implementation was calling `backtrace()` for every
function call, which is quite slow.

Instead, this implementation provides VM::stack_trace() which unwinds
the native stack, maps it through NativeExecutable::get_source_range
and combines it with source ranges from interpreted call frames.

fb7b4b9c59 LibJS/JIT: Provide source location information for JIT code
This works by walking a backtrace until the currently executing
native executable is found, and then mapping the native address
to its bytecode instruction.

dfaf645302 LibJS: Add an inline JIT fast path when ToNumeric has nothing to do
In most cases, this op will do nothing, as it is running on an the
accumulator while it already contains a number. Let's avoid doing that
native call.
