JVM Backend Support Utilities - Extracted utilities for bytecode generation.

This package contains focused utility classes extracted from the AbstractAsmGenerator base class, following the EK9 pattern of small, single-responsibility classes.

Context and State:

• MethodContext - Shared method context
• LocalVariableInfo - Local variable metadata
• ScopeInfo - Scope boundary tracking
• TempVariableSource - Temp variable sources

Bytecode Generation:

• LiteralBytecodeGenerator - Literal value generation
• VariableAccessGenerator - Variable load/store
• DebugInfoGenerator - Debug info and LocalVariableTable

These utilities are composed by AbstractAsmGenerator and used by the specialized AsmGenerator subclasses.

org.ek9lang.compiler.backend.jvm.debug

Class	Description
DebugInfoGenerator	Generates debug information for JVM bytecode.
Ek9MethodKind	THE closed taxonomy of EK9 compiler-generated method kinds carried by the Ek9MethodKinds class attribute (C.2), each with its debugger MethodDebugPolicy bitset.
Ek9MethodKindsAttribute	The versioned Ek9MethodKinds class attribute (C.2): a per-method map of (name, descriptor) -> Ek9MethodKind + MethodDebugPolicy bitset, letting the EK9 debug semantics layer decide step-filtering and frame re-presentation.
Ek9MethodKindsAttribute.Entry	One per-method record: the method (name, descriptor), the Ek9MethodKind wire kindCode, and its MethodDebugPolicy bitset.
JvmOpcodes	Shared JVM opcode selection for the bytecode generators: primitive/reference local-variable load/store opcodes and optimal integer-constant loading.
JvmSignatures	Shared construction of JVM method/constructor descriptors from already-JVM-internal type names.
LiteralBytecodeGenerator	Generates JVM bytecode for EK9 literal values.
LocalVariableInfo	Metadata for a local variable needed for LocalVariableTable generation.
MethodContext	Shared context for a method that must be coordinated across all generators.
MethodDebugPolicy	THE debugger step-filter / frame-decoder policy bits carried per generated method by the Ek9MethodKinds class attribute (C.2).
MethodKindTable	Per-class accumulator of Ek9MethodKind entries, populated as methods are emitted and turned into the Ek9MethodKinds class attribute just before visitEnd() (mirroring how the SMAP is collected then attached).
ScopeInfo	Scope boundary information for tracking variable lifetimes.
StackOperationSupport	Support for stack-oriented code generation.
TempVariableSource	Represents the source of a temp variable for stack-oriented code generation.
TempVariableSource.Type	The type of source for a temp variable.
VariableAccessGenerator	Generates JVM bytecode for variable load and store operations.
