Fix PR #150116 bug: incorrect memory index inversion in coroutine layout

[leonardocxavier]

This commit fixes a critical bug introduced in PR #150116 that caused "offset is not a multiple of 16" errors when compiling for x86_64-unknown-uefi.

Problem:

PR #150116 optimized memory layout by inverting the storage representation from memory_index (source→memory) to in_memory_order (memory→source).

However, in compiler/rustc_abi/src/layout/coroutine.rs (lines 244-276), the code was building combined_in_memory_order directly instead of:

1. Building combined_memory_index (source→memory) first
2. Inverting it to get in_memory_order (memory→source)

This caused fields to be placed at incorrect offsets, violating PE/COFF alignment requirements (16-byte multiples), triggering linker errors.

Solution:

Changed the coroutine layout code to:

• Build combined_memory_index as an intermediate representation
• Use correct indexing: combined_memory_index[i] = memory_index
• Invert at the end: combined_in_memory_order = combined_memory_index.invert_bijective_mapping()

Impact:

• Fixes UEFI target compilation (x86_64-unknown-uefi)
• May affect other PE/COFF targets
• Enables SOBEX OS development to continue

Files changed:

• compiler/rustc_abi/src/layout/coroutine.rs: Applied fix
• BUG_FIX_REPORT.md: Detailed investigation report
• fix_pr150116_coroutine_layout.patch: Patch for upstream submission
• .gitignore: Added Claude Code settings

Upstream:

This fix should be submitted to rust-lang/rust as it affects the latest nightly (2025-12-19) and potentially other PE/COFF targets.
