020726c981 update trans_c_stack_native_call() to use type_of_explicit_args() 
currently trans_c_stack_native_call() had some ad-hoc code for
determining the type of the arguments. this code was not in
agreement with the rest of trans. now it uses the same code path.

7114702496 Change the way block calls are parsed, mark them as block-calls. 
This makes it possible to omit the semicolon after the block, and will
cause the pretty-printer to properly print such calls (if
pretty-printing of blocks wasn't so broken). Block calls (with the
block outside of the parentheses) can now only occur at statement
level, and their value can not be used. When calling a block-style
function that returns a useful value, the block must be put insde the
parentheses.

0714bb5f7d Fix the problem with check-fast randomly failing 
Trans has been assuming that tag node id's are unique across crates and they
are not so, depending on which way the wind is blowing, it would choose to use
a crate-local tag variant instead of the correct one from std.

No test case since I can't come up with a reliable one that compiles in a
reasonable amount of time.

99f876e3a8 Make build_environment and trans_bind_thunk GEP bound arguments the same 
These functions both use GEP_tup_like to get at the arguments bound to the
environment, but they were starting from a different 'level' of the
environment-box structure. Frighteningly, this was leading to them having
different opinions of how the bound arguments were aligned in some cases.

b8bb663df7 Don't ever raise unique kinds of pinned kinds to shared (again) 
So *resource, ~resource, [resource] are all pinned. This is counter to the
design of the kind system, but this way is a much clearer path to type safety.
Once we've established a good baseline with lots of tests, then we can try to
make raising pinned kinds work.

420484579d Better handling of unreachable code in trans 
The builder functions in trans_build now look at an 'unreachable' flag
in the block context and don't generate code (returning undefined
placeholder values) when this flag is set. Threading the unreachable
flag through context still requires some care, but this seems a more
sane approach than re-checking for terminated blocks throughout the
compiler.

When creating a block, if you use its closest dominator as parent, the
flag will be automatically passed through. If you can't do that,
because the dominator is a scope block that you're trying to get out
of, you'll have to do something like this to explicitly pass on the
flag:

    if bcx.unreachable { Unreachable(next_cx); }
