Fix -Wlarge-by-value-copy option handling in the driver. CC1 supports only the joined format. llvm-svn: 156161

// RUN: %clang -### -Wlarge-by-value-copy %s 2>&1 | FileCheck -check-prefix=LARGE_VALUE_COPY_DEFAULT %s
// LARGE_VALUE_COPY_DEFAULT: -Wlarge-by-value-copy=64
// RUN: %clang -### -Wlarge-by-value-copy=128 %s 2>&1 | FileCheck -check-prefix=LARGE_VALUE_COPY_JOINED %s
// LARGE_VALUE_COPY_JOINED: -Wlarge-by-value-copy=128
Warn about -Wno-foo where foo is an unknown warning option. This is helpful for subtle misspellings such as -Wno-unused-command-line-arguments instead of -Wno-unused-command-line-argument. Also fix the diagnostic messages to properly handle -Wno- options. Previously, the positive version was always emitted (i.e., -Wfoo was emitted for -Wno-foo). rdar://11461500 llvm-svn: 156937

// RUN: %clang -c -Wmonkey -Wno-monkey -Wno-unused-command-line-arguments \

// CHECK: unknown warning option '-Wmonkey'
// CHECK: unknown warning option '-Wno-monkey'
Tweek r156937 a bit so that the suggestions are correct. llvm-svn: 156938

// CHECK: unknown warning option '-Wno-unused-command-line-arguments'; did you mean '-Wno-unused-command-line-argument'?
