.gnu.hash happen to contain only 32-bit integers for 32-bit arch,
but the section contents are not uniform array members, so setting
entsize doesn't make much sense. This behavior seems to have been
blindly copied from GNU linkers.

This is a shorthand for Config->Wordsize == 8. So this is not strictly
necessary but seems handy. "Is 64 bit?" is easier to read than "Is
wordsize 8 byte?"

Patch moves Sections array to
InputFile (root class for input files).
That allows to detemplate GdbIndexSection.

This continues detemplation process.
Detemplating MipsGotSection<ELFT> is helpfull because can
help to detemplate getRelocTargetVA. (one more change is required)
It opens road to detemplation of GotSection<ELFT> and probably
something else after that.

Does not introduce anything new,
just performs detemplate, using methods we
already have.

We had a few Config member functions that returns configuration values.
For example, we had is64() which returns true if the target is 64-bit.
The return values of these functions are constant and never change.
This patch is to compute them only once to make it clear that they'll
never change.

Do not take in account the `Live` flag while collecting .reginfo, .MIPS.options,
and .MIPS.abiflags input sections to produce corresponding output sections.
These sections have information purpose and should be always produced per
ABI requirements.

Original commit message:
Patch reuses BssSection section to simplify creation of
COMMON section.
Differential revision: https://reviews.llvm.org/D30690
llvm-svn: 298086
Was fixed, details on review page.
Original commit message:
That removes CopyRelSection class completely, making
Bss/BssRelRo to be just regular synthetics.
This is splitted from D30541 and polished.
Difference from D30541 that all logic of SharedSymbol
converting to DefinedRegular was removed for now and
probably will be posted as separate patch.

That allows to detemplate getGotPltOffset/getGotPltVA
methods of SymbolBody and also will help to detemplate
DynamicReloc itself later.

Patch splits In<ELFT> into 2 classes: one for non-templated sections,
second contains ELFT templated ones.
That allows to code that was detemplated to access non-templated sections freely,
and should open road for futher detemplation proccess.

After introducing Config->is64Bit() and
recent changes in LinkerScriptBase, some
sections can be detemplated trivially. This
is one of such cases.
llvm-svn: 297825
StringTableSection was <ELFT> templated previously,
It disallow to de-template code that uses it,
for example LinkerScript<ELFT>::discard uses it as:
if (S == In<ELFT>::ShStrTab)
error("discarding .shstrtab section is not allowed");
It seems we can try to detemplate some of synthetic sections
and somehow make them available for non-templated calls.
(move out of In<ELFT> struct probably).

Using .eh_frame input section pattern in linker script currently
causes a crash; this is because .eh_frame input sections require
special handling since they're all combined into a synthetic
section rather than regular output section.

gold linker manual describes them as:
-z text Do not permit relocations in read-only segments
-z notext Permit relocations in read-only segments (default)
In LLD default is to not permit them. Patch implements -z notext.

With this we have a single section hierarchy. It is a bit less code,
but the main advantage will be in a future patch being able to handle
foo = symbol_in_obj;
in a linker script. Currently that fails since we try to find the
output section of symbol_in_obj. With this we should be able to just
return an InputSection from the expression.
