c3bc8fada8 Allow omission of the '.' after nullary tag patterns 
This commit allows patterns like:

alt x { some(_) { ... } none { } }

without the '.' after none. The parser suspends judgment about
whether a bare ident is a tag or a new bound variable; instead,
the resolver disambiguates.

This means that any code after resolution that pattern-matches on
patterns needs to call pat_util::normalize_pat, which consults
an environment to do this disambiguation.

In addition, local variables are no longer allowed to shadow
tag names, so this required changing some code (e.g. renaming
variables named "mut", and renaming ast::sub to subtract).

The parser currently accepts patterns with and without the '.'.
Once the compiler and libraries are changed, it will no longer
accept the '.'.

08c16b17e9 Fix --pretty normal, reorganize some code in driver.rs 
There is now only one path doing crate expanding and typechecking,
which should make it less likely for the pretty-printing code to be
broken by changes to the compilation pipeline.

Closes #1536

1c7a62c93b Use a memset upcall to zero things without static alignment 
This fixes issues #843 and #1546. The cost of an upcall is
unfortunate, though. I assume there must be a way to simply manually
compute the pointer or size, using something akin to the formula in
`align_to` in `rust_util.h`. I could not get this to work,
unfortunately.

ef0775fec8 build: Check and set perf --log-fd option 
Linux perf tool version 3.2 introduced a new option "--log-fd" defaults
to 0, which leads to error "Failed opening logfd: Illegal argument" when
executing perf tests.

Set logfd to stderr to let perf test work.

e1c50c4410 Don't evaluate discriminator value constants when parsing. 
Remove disr_val from ast::variant_ and always use ty::variant_info
when the value is needed.  Move what was done during parsing into
other passes, primary typeck.rs.  This move also correctly type checks
the disr. value expression; thus, fixing rustc --pretty=typed when
disr. values are used.
