    MIPS/GAS/test: Fix an n32 `.reginfo' size test failure
    
    Correct a commit 2d6dda71611b ("MIPS/BFD: Correctly report unsupported
    `.reginfo' section size") issue and avoid a GAS test failure:
    
    regexp_diff match failure
    regexp "^.*: Incorrect `\.reginfo' section size; expected 24, got 28$"
    line   "../as-new: dump.o: Incorrect `.reginfo' section size; expected 24, got 32"
    FAIL: MIPS assembled .reginfo section size (n32)
    
    on MIPS targets other than bare-metal ones.  The reason for this failure
    is section padding to alignment, done in `size_seg'.  For n32 `.reginfo'
    the section alignment is set to 3, and therefore the section is padded
    to a multiple of 8, except for bare-metal targets, for which padding is
    unconditionally disabled in `md_section_align'.
    
    Use `--no-pad-sections' then to disable padding for all targets, so that
    the size of `.reginfo' is always the same, matching the message pattern.

    	* testsuite/gas/mips/reginfo-2-n32.d: Add `--no-pad-sections' to
    	`as' flags.
