7.8 Release Update

[Edward Z. Yang]

Hello Mikhail,

It is a known issue that Template Haskell does not work with profiling (because
GHCi and profiling do not work together, and TH uses GHCi's linker). [1] Actually,
with the new linker patches that are landing soon we are not too far off from
having this work.
