Subject: [PATCH 1/3] [flang] Complete alignment of -x language modes with
 gfortran

This fixes an issue where, since the alignment of the -x lanaguage
modes, .f90 files were being preprocessed by default. This patch
completes the alignment of the meaning of the f95-pp-input and f95
language modes to match gfortran, fixing that issue.

Other than the nit, this looks ok. However, I must admit that I don't fully 
understand the nuances of the various modes, and I got a bit lost with the 
previous PR as well, so I'll leave it to someone else to approve as they see 
fit.

Changes

This fixes an issue where, since the alignment of the -x lanaguage
modes, .f90 files were being preprocessed by default. This patch
completes the alignment of the meaning of the f95-pp-input and f95
language modes to match gfortran, fixing that issue.
