Douglas Yung e0ee228842 [clang][test] Fix test for external assemblers 
This test depends on using the integrated assembler, so make it
explicit by specifying -fintegrated-as.

Luboš Luňák 54eea6127c add -fpch-codegen/debuginfo mapping to -fmodules-codegen/debuginfo 
Using -fmodules-* options for PCHs is a bit confusing, so add -fpch-*
variants. Having extra options also makes it simple to do a configure
check for the feature.
Also document the options in the release notes.

Luboš Luňák 3895466e2c accept 'clang++ -c a.pch -o a.o' to create PCH's object file 
This way should be the same like with a.pcm for modules.
An alternative way is 'clang++ -c empty.cpp -include-pch a.pch -o a.o
-Xclang -building-pch-with-obj', which is what clang-cl's /Yc does
internally.
