This patch moves the applyBTIFixup from LongJmp pass to MCPlusBuilder.
This refactor allows applyBTIFixup to be called from other passes
inserting indirect branches, such as:
- Hugify,
- PatchEntries.
As different passes have different information about their targets (e.g.
target BasicBlock, target Symbol, target Function), specialized versions
are created (applyBTIFixupToSymbol, applyBTIFixupToTarget), and each
calls
applyBTIFixupCommon, which implements the original logic from before.
Names of related lit tests are updated to have the "bti" prefix.
