[PATCH] D61668: [ARM] Fix the extensions implied by a cpu name

When using `clang -mcpu=CPUNAME+FEATURELIST`,
the intrinsic features defined by CPUNAME are
not obtained, as the entire string is passed.
This fixes that by spiting the cpuname
string in the first `+`, if any.

For example, when using

  clang -### --target=arm-arm-none-eabi -march=armv7-a -mcpu=cortex-a8+nocrc

the intrinsic

  "target-feature" "+dsp"

implied by `cortex-a8` is missing.
