[PATCH] D58030: [bindings/go] Fix building on 32-bit systems (ARM etc.)

[Ayke via Phabricator via llvm-commits]

The patch in https://reviews.llvm.org/D53883 (by me) fails to build on 32-bit systems like ARM. Fix the array size to be less ridiculously large. 2<<20 should still be enough for all practical purposes.

Bug: https://bugs.llvm.org/show_bug.cgi?id=40426
