Remove unused and no-longer-needed function compilerCheck

[eddelbuettel]

During the previous PR I noticed this unused function from 2016 hanging around. A search under organization cran reveals no package using it, and we are generally in a better situation with respect to what the compilers provide / what we need. So while I am generally very careful about removals, this one should be easy.

Checklist

• Code compiles correctly
• R CMD check still passes all tests
• Preferably, new tests were added which fail without the change
• Document the changes by file in ChangeLog

Pull Request Overview

This PR removes the unused compilerCheck function and its documentation from the Rcpp package. The function was originally created in 2016 to check for minimal g++ compiler versions but is no longer needed due to improved compiler support and lack of usage across CRAN packages.

• Removes the compilerCheck function from R/compilerCheck.R
• Removes corresponding documentation from man/compilerCheck.Rd
• Updates package version from 1.1.0.1 to 1.1.0.2 with appropriate changelog entries

Wasn't exported, so shouldn't break anything.

Correct.

Next up are the exported and long-deprecated RcppLdPath() and friends and because they were exported I am fearing breakage. We shall see ...
