Elvina Yakubova b36a3e6140 [llvm-readobj] Update tests because of changes in llvm-readobj behavior
This patch updates tests using llvm-readobj and llvm-readelf, because
soon reading from stdin will be achievable only via a '-' as described
here: https://bugs.llvm.org/show_bug.cgi?id=46400. Patch with changes to
llvm-readobj behavior is here: https://reviews.llvm.org/D83704

Fangrui Song ecd6d7254e [test] llvm/test/: change llvm-objdump single-dash long options to double-dash options
As announced here: http://lists.llvm.org/pipermail/llvm-dev/2019-April/131786.html

Grouped option syntax (POSIX Utility Conventions) does not play well with -long-option
A subsequent change will reject -long-option.

Fangrui Song 6afcdcf9ab [llvm-readobj] Change -t to --symbols in tests. NFC
-t is --symbols in llvm-readobj but --section-details (unimplemented) in readelf.
The confusing option should not be used since we aim for improving
compatibility.

Keep just one llvm-readobj -t use case in test/tools/llvm-readobj/symbols.test

* Do not allow Disassembler decoding instructions that have size more
  than a number of input bytes.

Anton Korobeynikov 883c70959d [MSP430] Use R_MSP430_16_BYTE type for FK_Data_2 fixup
Linker fails to link example like this (simplified case from newlib
sources):

$ cat test.c

extern const char _ctype_b[];
struct _t { char *ptr; };
struct _t T = { ((char *) _ctype_b + 3) };
$ cat ctype.c

char _ctype_b[4] = { 0, 0, 0, 0 };
LD: test.o:(.data+0x0): warning: internal error: unsupported relocation error

We also follow gnu toolchain here, where 2-byte relocation mapped to
R_MSP430_16_BYTE, instead of R_MSP430_16.

Anton Korobeynikov 411773d227 [MSP430] Add support for .refsym directive
Introduces support for '.refsym' assembler directive.

From GCC docs (for MSP430):
'.refsym' - This directive instructs assembler to add an undefined reference
to the symbol following the directive. No relocation is created for this symbol;
it will exist purely for pulling in object files from archives.

Anton Korobeynikov 49045c6a0d [MSP430] Add MC layer
Reapply r346374 with the fixes for modules build.

Original summary:

This change implements assembler parser, code emitter, ELF object writer
and disassembler for the MSP430 ISA.  Also, more instruction forms are added
to the target description.
