Glob-import trans_build in other trans files

Move to a more lightweight builder system

You now do
bld::Ret(bcx, someval)
where you used to say
bcx.build.Ret(someval)
Two fewer boxes are allocated for each block context, and build calls
no longer go through a vtable.

Implement pattern guards

The syntax is

The condition may refer to any of the variables bound by the pattern.
When a guard fails, pattern-matching continues with the next pattern.

Handle alt on a _|_ - typed value

Return the result of the discriminant from trans_alt,

In trans, don't assume both sides of a binop have the same type
...
This was at least partially responsible for Issue 777.
The only solution I can think of is for trans to just not generate
code for a comparison if one or both sides has type _|_. Since
that means evaluating that subexpression diverges, it should be ok
to never do the comparison. Actually generating code for the
comparison would trip an LLVM assertion failure.

This is required so that assigning to these locals doesn't clobber

Similar for loop variables. Assigning to such variables is not safe
yet. Function arguments also remain a TODO.

Move a bunch of trans into trans_common, including the context structures.
...
Probably more should be moved or split off into other files. My algorithm
was something along the lines of: move the contexts and their transitive
dependencies along with some functions to work with them. I stopped when
I was going to have to start pulling glue generation, which really
should go into a trans_glue file.
