Now a function to parse -foo-bar is always named getFooBar.

Now that all special sections are SyntheticSections, we only need one
OutputSection class.

Feature is used for producing static-linked PIE executables
(https://gcc.gnu.org/ml/gcc/2015-06/msg00008.html)
And was implemented in GNU ld https://gcc.gnu.org/ml/gcc/2015-08/msg00099.html

I also found it in linux kernel build system,
though I think that x86/x64 bootloader does not really rely on it.
Seems it used for PPC though.

__ehdr_start should be pointing to ELF file headers, not program
headers.

This is a reland of D30319.

This reverts commit r296079.

With this we complete the transition out of special output sections,
and with the previous patches it should be possible to merge
OutputSectionBase and OuputSection.

llvm-svn: 296023

With the current design an InputSection is basically anything that
goes directly in a OutputSection. That includes plain input section
but also synthetic sections, so this should probably not be a
template.

If -z stack-size is given, we need to add PT_GNU_STACK even if
-z execstack is not given.

We have InputSection, MergeInputSection and EhInputSection, so
isa<MergeInputSection> is equivalent to !isa<InputSection> && !isa<
EhInputSection>.

We shouldn't report an error for R_*_NONE relocs since we're emitting
them when writing relocations to discarded sections.

This shouldn't change the meaning of the code.

Now that InputSectionBase is not a template there is no reason to have
the two.

llvm-svn: 295924

Removing this template is not a big win by itself, but opens the way
for removing more templates.

* Added comment.
* Pass std::string copy instead using move semantic.
