[PATCH, PR d/87824] Committed return min_align_of_type from alignsize hook.

[Iain Buclaw]

Hi,

This patch addresses some of the failing tests on x86_64-linux/-m32.
The failing tests in question checked that data with 'long' was
sufficiently aligned.

  assert((&var.longfield % long.alignof) == 0);

Where long.alignof was replaced with the result of TYPE_ALIGN_UNIT.

The D language expects the minimum alignment from .alignof, so on -m32
alignof should return 4 instead of 8.

Bootstrapped and ran D2 testsuite on x86_64-linux-gnu with
{-m64,-m32/-mno-sse/-mno-mmx,-mx32} runtest flags.

Committed to trunk as r266234.
