Andrew Kelley 632d143bff replace `a %% b` with `a catch b`

Andrew Kelley bb39e503c0 fix struct inside function referencing local const
closes #672

the crash and compile errors are fixed but structs
inside functions still get named after the functions
they're in. this will be fixed later.

Andrew Kelley d917815d81 explicitly return from blocks
instead of last statement being expression value

closes #629

Andrew Kelley 8bc523219c add labeled loops, labeled break, labeled continue. remove goto
closes #346
closes #630

regression: translate-c can no longer translate switch statements.
after #629 we can ressurect and modify the code to utilize arbitrarily
returning from blocks.

Andrew Kelley 960914a073 add implicit cast from enum to union

to be of a void field of the union

Andrew Kelley 0ad1239522 rework enums and unions and their relationship to each other
* @enumTagName renamed to @tagName and it works on enums and
   union-enums
 * Remove the EnumTag type. Now there is only enum and union,
   and the tag type of a union is always an enum.
 * unions support specifying the tag enum type, and they support
   inferring an enum tag type.
 * Enums no longer support field types but they do support
   setting the tag values. Likewise union-enums when inferring
   an enum tag type support setting the tag values.
 * It is now an error for enums and unions to have 0 fields.
 * switch statements support union-enums

Andrew Kelley 634e8713c3 add @memberType and @memberName builtin functions
see #383

there is a plan to unify most of the reflection into 2
builtin functions, as outlined in the above issue,
but this gives us needed features for now, and we can
iterate on the design in future commits

Andrew Kelley c5c9d98065 introduce align keyword
* remove `@setGlobalAlign`
 * add align keyword for setting alignment on functions and
   variables.
 * loads and stores use alignment from pointer
 * memcpy, memset use alignment from pointer
 * add syntax for pointer alignment
 * slices can have volatile
 * add u2, i2 primitives
 * ignore preferred align and use abi align everywhere
 * back to only having alignOf builtin.
   preferredAlignOf is too tricky to be useful.

 * >> is right shift, allowed to shift 1 bits out

After:
 * << is left shift, allowed to shift 1 bits out
 * >> is right shift, allowed to shift 1 bits out
 * @shlExact is left shift, not allowed to shift 1 bits out
 * @shrExact is right shift, not allowed to shift 1 bits out
