Rafael Espindola ccd3adc60b lit fixes for lld.
It was not using LLVM_LIT_TOOLS_DIR and at least on my VM never finding lib.exe.

With this all the COFF tests show up as supported and pass.

Rui Ueyama ba7c041f21 COFF: ARM: Implepment BLX23T relocation and fix Branch20T.
I fed the same test to MSVC linker and got the same output,
so I believe this implementation is correct.

The writer is still hard coded to 64 bits le, but with this we can test for

Reid Kleckner 60dde1fbda Disable objdump disassembly test after r243755
Right now PE image section addresses are RVAs and symbol addresses are
VAs.  We should probably fix this by changing section addresses to match
symbol addresses. Fixing this might take a few hours, so temporarily
disable the objdump part of this test.

Rui Ueyama eb26e1d03c COFF: Fix SECREL and SECTION relocations.
SECREL should sets the 32-bit offset of the target from the beginning
of *target's* output section. Previously, the offset from the beginning
of source's output section was used instead.

SECTION means the target section's index, and not the source section's
index. This patch fixes that issue too.

Rui Ueyama 9420dee328 COFF: Fix export symbol names for x86.
I don't fully understand the rationale behind the name mangling
scheme used for the DLL export table and the import library.
Why only leading "_" is dropped for the import library while
both "_" and "@" are dropped from DLL symbol table? But this seems
to be what MSVC linker does.

Rui Ueyama cfb874a3d4 COFF: Do not ignore /merge if /debug is specified.

Rui Ueyama cd3f99b6c5 COFF: Implement Safe SEH support for x86.
An object file compatible with Safe SEH contains a .sxdata section.
The section contains a list of symbol table indices, each of which
is an exception handler function. A safe SEH-enabled executable
contains a list of exception handler RVAs. So, what the linker has
to do to support Safe SEH is basically to read the .sxdata section,
interpret the contents as a list of symbol indices, unique-fy and
sort their RVAs, and then emit that list to .rdata. This patch
implements that feature.

Rui Ueyama 3cb895c930 COFF: Fix __ImageBase symbol relocation.
__ImageBase is a special symbol whose value is the image base address.
Previously, we handled __ImageBase symbol as an absolute symbol.

Absolute symbols point to specific locations in memory and the locations
never change even if an image is base-relocated. That means that we
don't have base relocation entries for absolute symbols.

This is not a case for __ImageBase. If an image is base-relocated, its
base address changes, and __ImageBase needs to be shifted as well.
So we have to have base relocations for __ImageBase. That means that
__ImageBase is not really an absolute symbol but a different kind of
symbol.

In this patch, I introduced a new type of symbol -- DefinedRelative.
DefinedRelative is similar to DefinedAbsolute, but it has not a VA but RVA
and is a subject of base relocation. Currently only __ImageBase is of
the new symbol type.
