[patch] for PR26327

[Uttam Pawar <uttamp at us dot ibm dot com>]

Hello,

The following patch fixes the reported memory leaks. I also noticed the fix by Sebastian Pop, for a memory leak
in gcc/tree-if-conv.c (ignored from this patch).

Bootstrapped on powerpc64-linux. Testing (make check) showed no new regressions.

Thanks,

Uttam
