make_dynamic_error_code was used to create a std::error_code with
a std::string message. Now that we are migrating to llvm::Error,
there are no calls to these make_dynamic_error_code methods.
There is one single call to make_dynamic_error_code remaining, the one
inside GenericError::convertToErrorCode(). That method is only called
from File::doParse() which should be a temporary situation. We need
to work out how to deal with File::parse() caching the error result from
doParse(). Caching errors isn't supported in the new scheme, and probably
isn't needed here, but we need to work that out.
Once thats done, dynamic error and all utilities around it can be deleted.

Adds a GenericError class to lld/Core which can carry a string. This is
analygous to the dynamic_error we currently use in lld/Core.
Use this GenericError instead of make_dynamic_error_code. Also, provide
an implemention of GenericError::convertToErrorCode which for now converts
it in to the dynamic_error_code we used to have. This will go away once
all the APIs are converted.

Add PT_PHDR segment depending on its availability in linker script's
PHDRS command, fallback if no linker script is given.
Handle FILEHDR, PHDRS and FLAGS attributes of program header.

Add method to query segments for specified output section name.
Return error if the section is assigned to unknown segment.
Check matching of sections to segments during layout on the subject of correctness.
NOTE: no actual functionality of using custom segments is implemented.

The function took either StringRef or Twine. Since string literals are
ambiguous when resolving the overloading, many code calls used this
function with explicit type conversion. That led awkward code like
make_dynamic_error_code(Twine("Error occurred")).
This patch adds a function definition for string literals, so that
you can directly call the function with literals.

The Native file format was designed to be the fastest on-memory or
on-disk file format for object files. The problem is that no one
is working on that. No LLVM tools can produce object files in
the Native, thus the feature of supporting the format is useless
in the linker.
This patch removes the Native file support. We can add it back
if we really want it in future.

The expression evaluation is needed when interpreting linker scripts, in order
to calculate the value for new symbols or to determine a new position to load
sections in memory. This commit extends Expression nodes from the linker script
AST with evaluation functions, and also contains a unit test.

ReaderErrorCategory was used only at one place. We now have a
DynamicErrorCategory for this kind of one-time error, so use it.
The calling function doesn't really care the type of an error, so
ReaderErrorCategory was actually dead code.

These member functions returns either no_more_files error or a File object.
We could simply return a nullptr instead of a no_more_files.
This function will be removed soon as a part of InputGraph cleanup.
I had to do that step by step.

Previously, we would not check the target machine type and the module (object)
machine type. Add a check to ensure that we do not attempt to use an object
file with a different target architecture.
This change identified a couple of tests which were incorrectly mixing up
architecture types, using x86 input for a x64 target. Adjust the tests
appropriately. The renaming of the input and the architectures covers the
changes to the existing tests.
One significant change to the existing tests is that the newly added test input
for x64 uses the correct user label prefix for X64.

Rather than a series of cascading ifs, use a switch statement to convert the
error code to a string. This has the benefit of allowing the compiler to inform
us if we ever add a new error code but fail to update the string representation.
Add in stringified versions for a couple of missing InputGraphErrors.

This code was never being used and any use of it would look fairly strange.
For example, it would try to map a NativeReaderError::file_malformed to
std::errc::invalid_argument.
