Rui Ueyama 103e03040b Add a test for r233128: PECOFF: Reduce import table size.
This test checks for the size of .idata section. Before r233128,
the size of the section is 0x45, but it's now 0x27.

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.

Rui Ueyama 6cfe07b9eb [PECOFF] Emit the import table to .idata section.
Emitting idata atoms to their own section would make debugging easier.
The Windows loader do not really care about whether the DLL import table is
in .rdata or its own .idata section, so there is no change in functionality.

Rui Ueyama 3e873b0578 [PECOFF] Add a generic section writer.
Instead of having multiple SectionChunks for each section (.text, .data,
.rdata and .bss), we could have one chunk writer that can emit any sections.
This patch does that -- removing all section-sepcific chunk writers and
replace them with one "generic" writer.

This change should simplify the code because it eliminates similar-but-
slightly-different classes.

It also fixes an issue in the previous design. Before this patch, we could
emit only limited set of sections (i.e. .text, .data, .rdata and .bss). With
this patch, we can emit any sections.

Shankar Easwaran 89c2d8faca [PassManager] add ReaderWriter{Native,YAML} to the Driver.
Disable tests to be run with REQUIRES: disable. Note disable is not added to the
config by the test runner Mkaefiles, so essentially disables the test.

Shankar Easwaran f1b341c80e [lld][LayoutPass] Order the atoms that are in the same chain
We need to order atoms that exist in the same chain. This is to make sure that
the command line order is preserved when we emit the atoms to the output file.

Credits: BigCheese for finding the bug.

Adds a test which otherwise would fail.

Rui Ueyama f1ffe8abbf [PECOFF] Trim at most one character from imported symbols.
The import name is not always the same as the symbol name. If the name/type
field in the import header is NOPREFIX or UNDECORATE, we need to strip some
characters from symbol to get its import name.

The Microsoft PE/COFF spec is vague if symbol contains more than two
consecutive characters to be stripped. We used to strip all characters,
but it doesn't seem right as we couldn't link against the system library
because of this name mangling. Looks like we shouldn't strip more than one
character.

Rui Ueyama b469aeb164 [PECOFF] Process Import Name/Type field in the import library.
This patch removes hacky mangle() function, which strips all decorations
uncondtitionally. LLD now interprets Import Name/Type field in the import
library properly as described in the Microsoft PE/COFF Spec.

This patch adds a new pass, IdataPass, to transform shared atom references
to real references and to construct the .idata section data. With this patch
lld can produce a working Hello World program by linking it against
kernel32.dll and user32.dll.
