Previously, mkpackage jumbled together three unrelated tasks: handling
package declarations, clearing imports from processing previous source
files, and assigning a default value to outfile.

XPos is a compact (8 instead of 16 bytes on a 64bit machine) source
position representation. There is a 1:1 correspondence between each
XPos and each regular Pos, translated via a global table.
In some sense this brings back the LineHist, though positions can
track line and column information; there is a O(1) translation
between the representations (no binary search), and the translation
is factored out.
The size increase with the prior change is brought down again and
the compiler speed is in line with the master repo (measured on
the same "quiet" machine as for prior change):

This replaces the src.Pos LineHist-based position tracking with
the syntax.Pos implementation and updates all uses.
The LineHist table is not used anymore - the respective code is still
there but should be removed eventually. CL forthcoming.
Passes toolstash -cmp when comparing to the master repo (with the
exception of a couple of swapped assembly instructions, likely due
to different instruction scheduling because the line-based sorting
has changed; though this is won't affect correctness).
The sizes of various important compiler data structures have increased
significantly (see the various sizes_test.go files); this is probably
the reason for an increase of compilation times (to be addressed). Here
are the results of compilebench -count 5, run on a "quiet" machine (no
apps running besides a terminal):

func f() {

}
We mistakenly don't add a frame pointer for f. This means f
isn't seen when walking the frame pointer linked list. That
matters for kernel-gathered profiles, and is an impediment for
issues like #16638.
To fix, allocate a stack frame even for otherwise frameless functions
like f. It is a bit tricky because we need to avoid some runtime
internals that really, really don't want one.
No test at the moment, as only kernel CPU profiles would catch it.
Tests will come with the implementation of #16638.
Fixes #18103

This fixes a bug in -l=3 or higher.
To inline a variadic function, the compiler generates code that constructs
a slice of arguments for the variadic parameter. Consider the function
func Foo(xs ...string)
and the call Foo("hello", "world"). To inline the call to Foo, the
compiler used to generate
xs := [2]string{"hello", "world"}[:]
which doesn't type check:
invalid operation [2]string literal[:] (slice of unaddressable value).
Now, the compiler generates
xs := []string{"hello", "world"}
which does type check.
Fixes #18116.

The doc field is not yet used - remove it for now (we may end up
with a different solution for 1.9). This reduces memory consumption
for parsing all of std lib by about 40MB and makes parsing slightly
faster.
