lirent 79e82ffc6a Add code-structure analysis: call graph, jump tables, basic blocks, constant xref
Wave 1 of the code-analysis layer, built on the x86-64 decoder:

- vmie_win32_callgraph walks each .pdata function with the decoder and emits an
  edge for every direct call/jmp whose target lands in the module - the
  intra-module call graph. Indirect edges are left to the IAT and jump tables.
- gva_jumptable recovers a switch's case targets from an indirect jump's table:
  consecutive pointer entries that land in an executable region.
- cfg_blocks splits one function view into basic blocks (a generic handler:
  leaders from intra-function branch targets, cut after jmp/jcc/ret).
- gva_imm_xref finds the instructions whose immediate operand equals a constant
  - the dual of code-xref for magic values, error codes, syscall numbers.

The decoder now also reports imm_off/imm_len so a caller can read or match the
immediate operand. The generic primitives live in the new codeanalysis.h
(jump tables, basic blocks) and scan.h (constant xref); the .pdata-bound call
graph stays on the win32 surface and reuses the existing function/section/decode
primitives - no second PE or instruction parser.
