Pete Cooper eadf9e4ec9 Remove unused variants of make_dynamic_error_code. NFC.
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.

Pete Cooper 1e00911ee0 Change getReferenceInfo/getPairReferenceInfo to use new Error handling. NFC.
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.

Rui Ueyama e75e50c045 Define make_dynamic_error_code(const char *).
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.

Rui Ueyama aa7b304ea7 Remove the Native file format.
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.

Rafael Auler ad11d4c196 [LinkerScript] Implement linker script expression evaluation
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.

Rui Ueyama 7da4037c81 Replace ReaderError with DynamicError.
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.

Rui Ueyama e9b455184f Simplify InputGraph API.
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.

Saleem Abdulrasool 6211740789 PE/COFF: add a check to ensure that we dont mix up architectures
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.

Saleem Abdulrasool 1277faf54d Core: switch error mapping to switches
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.

Rafael Espindola b34440f9c4 Remove unused and odd code.
This code was never being used and any use of it would look fairly strange.

std::errc::invalid_argument.

Nick Kledzik 181ce5ee03 Add make_dynamic_error_code().
This is a short-term fix to allow lld Readers to return error messages
with dynamic content.  

The long term fix will be to enhance ErrorOr<> to work with errors other
than error_code.  Or to change the interface to Readers to pass down a
diagnostics object through which all error messages are written.

Shankar Easwaran d87a021c79 [InputGraph][Gnu] Add LinkerScript support.
This adds LinkerScript support by creating a type Script which is of type
FileNode in the InputGraph. Once the LinkerScript Parser converts the
LinkerScript into a sequence of command, the commands are handled by the
equivalent LinkerScript node for the current Flavor/Target. For ELF, a
ELFGNULdScript gets created which converts the commands to ELF nodes and ELF
control nodes(ELFGroup for handling Group nodes).

Since the Inputfile type has to be determined in the Driver, the Driver needs
to determine the complete path of the file that needs to be processed by the
Linker. Due to this, few tests have been removed since the Driver uses paths
that doesnot exist.

Summary:
The original code with enum "_" is intended to emulate scoped enums.
