[ELF] Support high address DW_EH_sdata4 for ELFCLASS32
When the address pointer encoding in FDEs uses
DW_EH_PE_absptr|DW_EH_PE_sdata4, the address is sign-extended to 64-bit
by `readFdeAddr`. We should truncate the address to 32-bit for
ELFCLASS32. Otherwise, `isInt<32>(pc - va)` could be false, leading to a
spurious error in `getFdeData`.
In LLVM, this appears a MIPS-specific issue.
Fix #88852
