[llvm][IfConversion] update successor list when merging INLINEASM_BR
If this successor list is not correct, then branch-folding may
incorrectly think that the indirect target is dead and remove it. This
results in a dangling reference to the removed block as an operand to
the INLINEASM_BR, which later will get AsmPrinted into code that doesn't
assemble.
This was made more obvious by, but is not a regression of
https://reviews.llvm.org/D130316.
