This is the second attempt. We should be inserting the Driver
features in front of the features of a parsed target attribute
to avoid errors like the following:
```
% cat neon.c
__attribute__((target("arch=armv8-a")))
uint64x2_t foo(uint64x2_t a, uint64x2_t b) { return veorq_u64(a, b); }
% clang --target=aarch64-linux-gnu -c neon.c
error: always_inline function 'veorq_u64' requires target feature
'outline-atomics', but would be inlined into function 'foo'
that is compiled without support for 'outline-atomics'
```
