Previously we would generate a local variable pointing after the array

header and use it to initialize the array elements. But we already use

stores with offset, so it's easy to just add the header to those offsets

during compilation and avoid generating the local variable (which would

become a LEA instruction when using native codegen; LLVM already

optimizes it away).

Makes the width of STG dumps slightly saner.

Especially for things like unboxing.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Tagless final encoding of ExpCmdI in the parser

Before this change, we used a roundabout encoding:

1. a GADT (ExpCmdG)

2. a class to pass it around (ExpCmdI)

3. helpers to match on it (ecHsApp, ecHsIf, ecHsCase, ...)

It is more straightforward to turn these helpers into class methods,

removing the need for a GADT.
