[HIPIFY] Add hipconvertinplace2.sh and hipexamine2.sh scripts for hipify-clang.

The differences from the similar scripts for hipify.pl:
1. CSV file with extended statistics is produced.
2. scripts' arguments are changed a bit:
DIRNAME [hipify options] [--] [clang options]

where -- is a delimiter; all the arguments are optional, except DIRNAME.

Usage example:
./hipexamine2.sh ./tmp -o-stats ./tmp/stats.csv -- -I/usr/local/cuda-7.5/include -I/usr/local/hipify-clang/hipblas/include 2>&1 | tee log
