Always emit the letter 'E' in list-directed REAL output;
the library was omitting it for exponents greater than 99,
as should be done for E and D formatting of large exponents
without an Ed exponent digit count.

MSVC does not support a distinct 80-bit extended precision
"long double" type. Rework the I/O runtime to avoid using
native C/C++ type names. Centralize the mappings between
the KIND= type parameters of REAL and their binary precisions
in the common real.h header file, and use KIND type parameter
values rather than binary precisions for clarity where
appropriate.
This patch, if successful, should obviate the need for
Differential review D88511.
(This patch anticipates a successful review of D88688, which
fixes the function that maps each kind of real to its maximum
number of significant decimal digits.)

The sign of the scaling factor was misinterpreted for output
as meaning what it does for input. To be correct, they
should cancel each other out.
print '(1P,F4.3)', 1. ! printed 0.1 but should print 10.0

Tweak binary->decimal conversions to avoid an integer multiplication
in a hot loop to improve readability and get a minor (~5%) speed-up.
Use native integer division by constants for more readability, too,
since current build compilers seem to optimize it correctly now.
Delete the now needless temporary work-around facility in
Common/unsigned-const-division.h.

The estimation of the decimal exponent needs to allow for all
'd' of the requested significant digits.
Also accept a plus sign on a "+kP" scaling factor in a format.

Summary: For Lw output editing, emit (w-1) blanks before the T or the F.

flang/module only contains Fortran files and one is a .h so disable
formatting on that directory.

Fix F output editing in the Fortran runtime so that it
respects the 'd' count of digits after the decimal mark.

Summary:
Fix decimal formatting of 80-bit x87 values; the calculation ofnearest neighbor values failed to account for the explicitmost significant bit in that format.
Replace MultiplyByRounded with MultiplyBy in binary->decimal conversions,
since rounding won't happen and the name was misleading; then remove
dead code, and migrate LoseLeastSignificantDigit() from one source file
to another where it's still needed.
