Nikita Smith d1b055c62f Ignore S_REGREL32 during conversion of optimized procedures. 
In optimized builds, MSVC emits parameters as both S_LOCAL and S_REGREL32.
Most likely because their debugger relies on S_REGREL32 to format
parameters in the call stack window.

Nikita Smith 7f701dd806 minor fix 2025-11-26 20:31:34 -08:00
Nikita Smith f9561cb618 add support for CFA in the eval system 
Canonical Frame Address is a DWARF-only concept encoded in the unwind info.
Debugger must store this data for each call frame and provide it to
the eval system based on selected stack frame.

To abstract over format details, we introduce a "Frame Unwind Context".
For DWARF, this context maintains the intermediate unwind state and exposes
the CFA, whereas for PE, it remains empty.
