8aea1498c5 For now, solve the precision problem with brute force, 
by using long double where available.
Unfortunately, it won't be available everywhere, so a better solution
would still be nice.
Also, sometimes rounding of smaller sizes doesn't work right yet.

6f7e7963bc small (1 and 2 word) floating point literals not parsed correctly 
Fix gitlab issue #5.

The parse_float() function has several bugs:

    1. For 1- and 2-word floats it will always write all 4 bytes if the value is
       exactly 0.
    2. It incorrectly rounds and normalizes 1- and 2-word floats.

To see the issue easily try the following inputs:

     .flt2  1.0
     .flt4  1.0

These will assemble as '040100 000000' and '040200 000000 000000 000000'.
They should both begin '040200'.

In fact the test file test/test-prec.mac is incorrect in its only floating point value:
	.word	^f 1.5		; 040140
should actually assemble as 040300, not 040140 (040140 is actually ^F0.875).
I confirmed this on RT-11 running MACRO V05.06.

I fixed the problem with the following deltas:

[the patch]

The most crucial change is the very last one. 0x200000000000 is actually (1 << 45)
and because ufrac is normalized it means that it will always downshift ufrac by 1.

43aef73305 Fix logical error in listing from maclib. 
It seems the code was similarly wrong before I introduced the flag
CALLED_NOLIST in f07c9045f5bf60ccd821a33bb4ebf06d06fe7c48.

No change in regression tests as we don't have macro libraries available
to test.

88d33fd913 Adjust 2.11BSD-m11-lout.lst.ok. 
Because of this corrected sequence:

      575        000000                  lctbas  =       .
      576 000000                                genlct  seq
        1        000001                  lc.seq=        1
-       2                                       .rept   <.-lctbas>/2
+       2        000000                         .rept   <.-lctbas>/2
        3                                lc.seq=        lc.seq+lc.seq
        4                                       .endm
-       1        000002                  lc.seq=        lc.seq+lc.seq
        5 000000 073631                         .rad50  /seq/
        6                                       .if nb  <>
        7                                       lcinit= lcinit+lc.seq
        8                                       .endc

The repeat count is 0. lc.seq previously incorrectly had a value of 2
but now it has the correct value of 1.
This has a knock-on effect on various other expressions throughout, so there
are various changes.
