[If Converter] Convert recursion to iteration.
This commit makes changes to IfConverter::AnalyzeBlock to use iteration instead
of recursion. Previously, this function would get called recursively a large
number of times and eventually segfault when a function with the following CFG
was compiled:
BB0:
if (condition0)
goto BB1
goto BB2
BB1:
goto BB2
BB2:
if (condition1)
goto BB3
goto BB4
BB3:
...
(repeat until BB7488)
