[TestMiVar] Enable one of the tests for GCC.

[sivachandra]

Summary

The "internal" name of vars is different between clang and GCC. All this
change does is to use a regex instead of the hardcoded internal name.

I do not understand MI enough to judge whether a $13 instead of a $11 in the expectation is OK or not.

At the moment it's ok to use \d+ pattern to fix this test for gcc, but actually it should be the var6.*argv[0]. I'll check/fix it later.

BTW, do the 1 thing for me please.

test/tools/lldb-mi/variable/TestMiVar.py

121–122

Add a FIXME comment that the name is wrong and it should be equal to "var.*argv[0]"

[sivachandra]

Added the FIXME.
