Fix type-o with ___always_inline that broke clang build in r23558

[discussed via chat]

I accidentally left off a _, which works for gcc, but not for clang.
This started a discussion that maybe we should rename this #define to
something more clear like chpl_always_inline.

Stop hiding the annotations button on performance graphs

We have performance annotations now!

The annotations are hidden by default, but clicking the annotations button
next to the log button, will show them for that graph. Might want to add a
global option as well, but we'll see.
