Summary:                    Semicolon in AIX compiler warning FAIL_REFEX causes
it to match other output
Description: 
In CMakeCheckCompilerFlagCommonPatterns.cmake of CMake-3.0, the FAIL_REGEX
string for AIX contains a semicolon. This appears to cause the string to be
split in two entries (since CMake uses semicolon as a separator for lists).

Since the part after the semicolon is merely the word "ignored", any compiler
producing that word in the output will have a failure triggered.

Steps to Reproduce: 
We found this when using the Intel 12.1.0 compiler on Windows HPC 2008 since
that emits the linker warning "LINK : warning LNK4224: /INCREMENTAL:YES is no
longer supported;  ignored", which caused the above test to trigger for the
"ignored" word.



Additional Information: 
Suggest to replace semicolon with a period to match any character in the regular
expression.
