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.
