PR preprocessor/58580 - preprocessor goes OOM with warning for zero literals

In this problem report, the compiler is fed a (bogus) translation unit
in which some literals contain bytes whose value is zero.  The
preprocessor detects that and proceeds to emit diagnostics for that
king of bogus literals.  But then when the diagnostics machinery
re-reads the input file again to display the bogus literals with a
caret, it attempts to calculate the length of each of the lines it got
using fgets.  The line length calculation is done using strlen.  But
that doesn't work well when the content of the line can have several
zero bytes.  The result is that the read_line never sees the end of
the line because strlen repeatedly reports that the line ends before
the end-of-line character; so read_line thinks its buffer for reading
the line is too small; it thus increases the buffer, leading to a huge
memory consumption and disaster.

Here is what this patch does.

location_get_source_line is modified to return the length of a source
line that can now contain bytes with zero value.
diagnostic_show_locus() is then modified to consider that a line can
have characters of value zero, and so just shows a white space when
instructed to display one of these characters.

Additionally location_get_source_line is modified to avoid re-reading
each and every line from the beginning of the file until it reaches
the line number N that it is instructed to get; this was leading to
annoying quadratic behaviour when reading adjacent lines near the end
of (big) files.  So a cache is now associated to the file opened in
text mode.  When the content of the file is read, that content is
stashed in the file cache.  That file cache is searched for line
delimiters.  A number of line positions are saved in the cache and a
number of file caches are kept in memory.  That way when
location_get_source_line is asked to read line N + 1, it just has to
start reading from line N that it has already read.

new function.

going until we reach the size of the line.

* exp_ch3.adb (Expand_N_Object_Declaration): When a class-wide
object is declared, it is rewritten as a renaming of an dynamic
expression that wraps the initial value.  The renaming declaration
is first given an internal name, to prevent collisions with the
entity already declared, and then the name is modified to reflect
the original one. the modification of the name must preserve
the source location of the original, to prevent spurious errors
when compiling with style checks if the declaration involves
more than one entity.
