Implement the go:linkname compiler directive for functions (both

Rewrite the compiler directive support to recognize all the compiler
directives implemented by the current gc compiler. The directives other
than go:linkname are now turned into GOPRAGMA flags attached to a
function or function declaration. The go:linkname directive is turned
into a map attached to the Lex object. No new directives are actually
implemented yet, they are just recognized.

There were some reports that the autofdo tests are non deterministic
with parallel builds. I wasn't able to reproduce this, but here are
two changes that may help:
- Always use unique file names for temporary files.
- Don't print file names in the test log because the directories
can vary (suggested by Jeff Law)

We already lowered the limit of recursive template invocations from
100,000 to 10,000, but the tests still fail occasionally on
x86_64-pc-linux-gnu when using GNU ld (so that split stacks are not
fully functional). Reduce the limit further, to 1000, enough so that
the test passes consistently.
Permitting 1000 recursive template invocations still seems capacious
enough for real world use.
