[Driver] Make -print-libgcc-file-name print compiler-rt lib when used Make the -print-libgcc-file-name option print an appropriate compiler runtime library, that is libgcc.a if gcc runtime is used and an appropriate compiler-rt library if that runtime is used. The main use for this is to allow linking executables built with -nodefaultlibs (e.g. to avoid linking to the standard C++ library) to the compiler runtime library, e.g. using: clang++ ... -nodefaultlibs $(clang++ ... -print-libgcc-file-name) in which case currently a program built like this linked to the gcc runtime unconditionally. The patch fixes it to use compiler-rt libraries instead when compiler-rt is the active runtime. Differential Revision: https://reviews.llvm.org/D25338 llvm-svn: 283746

Reland r311836 - [Driver] Use arch type to find compiler-rt libraries (on Linux) Use llvm::Triple::getArchTypeName() when looking for compiler-rt libraries, rather than the exact arch string from the triple. This is more correct as it matches the values used when building compiler-rt (builtin-config-ix.cmake) which are the subset of the values allowed in triples. For example, this fixes an issue when the compiler set for i686-pc-linux-gnu triple would not find an i386 compiler-rt library, while this is the exact arch that is detected by compiler-rt. The same applies to any other i?86 variant allowed by LLVM. This also makes the special case for MSVC unnecessary, since now i386 will be used reliably for all 32-bit x86 variants.

[Driver] Register effective triple before get arm float abi. Summary: We need to register effective triple before calling `getARMFloatABI`. Add missing code when `--print-libgcc-file-name` is passed.
