vhdlpp: Out & inout arguments in subprogram calls are turned to registers.
...
Otherwise it is not possible to modify their values in subprograms.
Argument elaboration has been moved to a separate function, so now it is
common for procedure and function calls.

vhdlpp: CHARACTER type is converted to bit[7:0] instead of byte.
...
This way it is possible to have limited size strings. Previously they
were translated to unpacked array of bytes, which cannot be assigned as
it was a string.

warnings in new and old glibc versions, both _DEFAULT_SOURCE and _SVID_SOURCE
must be defined.

Before this patch, only literals on the right side of a < compare
(or left side of a > compare) would be blended into a %cmpi instruction.
This patch broadends the cases where the %cmpi can be used.

Have scope auto-rename generate names that use the index numbers
...
In generate blocks such as for loops, there may be many generated
scopes that have the same generated name. But in these cases, there
is an index number in the hname that can be used. So do so.

Fix for GitHub issue #79 - literal numbers must have at least one digit.
...
The bug report was for an assertion failure when a number contained only
a lowline (e.g. 'b_), but the standard says that a number can't start
with a lowline (e.g. 'b_1). The parser already rejected these cases for
decimal numbers, but allowed them through for binary/octal/hex numbers.

Fix for br991 - compiler crashes due to null statements.
...
The reported problem was caused by a null statement in a case statement,
which caused the check for an infinite loop to fail. Further testing
exposed more problems with null statements in loop statements - these
caused crashes earlier in elaboration.
