[ELF] - Basic support of linkerscript commands: DATA_SEGMENT_ALIGN, DATA_SEGMENT_END, CONSTANT
It is called basic because:
CONSTANT expression can refer to COMMONPAGESIZE and MAXPAGESIZE.
This sizes are usually different and used for possible optimization of
memory consumption.
More details are here: https://sourceware.org/ml/binutils/2002-02/msg00265.html
We currently do not support this optimization, so both CONSTANT(MAXPAGESIZE)
and CONSTANT(COMMONPAGESIZE) just return Target->PageSize value.
DATA_SEGMENT_ALIGN and DATA_SEGMENT_END are used as a part of opt.
The latter one is just ignored now.
According to documentation DATA_SEGMENT_ALIGN has 2 possible
calculation, but since we do not support mentioned opt - it
is always calculated now as (ALIGN(MAXPAGESIZE) + (. & (MAXPAGESIZE - 1))).
In general this should work for now until we deside to support this opt.
