Scan inlinable methods for references to global variables and
functions (forgot to do that earlier).
Track all packages mentioned by exports (that should have been done
earlier too).
Record assembler name in export data, so that we can inline calls to
non-Go functions. Modify gccgoimporter code to skip assembler name.
This increases the number of inlinable functions in the standard
library from 215 to 439.

When converting a constant to interface, such as interface{}(42)
or interface{}("hello"), if the interface escapes, we currently
generate a heap allocation to hold the constant value.
This CL changes it to generate a static allocation instead, as
the gc compiler does. This reduces allocations in such cases.

For PR60531, GCC wrongly rejects function templates with explicitly

does work.

We want to evaluate the arguments to a call before looking into the cache so
that we have constant values, but if we then find the call in the cache we
end up with a TREE_LIST that we don't end up using; in highly recursive
constexpr evaluation this ends up being a large proportion of the garbage
generated.
The cxx_eval_increment_expression hunk is less important, but it's an easy
tweak; we only use the MODIFY_EXPR to evaluate it, so after that it's
garbage.
