Align pragma broken

[rokups]

type Foo {.align: 16.} = object

Results in:

test.nim(2, 17) Error: invalid pragma: align: 16

Would be great if following worked as well:

type Foo = ref object
  bar {.align: 16.}: SomeType

Where SomeType is possibly importc type (if it is of any meaning).

Most ideally we would want following to work so that Foo type can be aligned as required always.

type Foo {.align: 16.} = object
