* Add --no-show-raw-insn to llvm-objdump -d tests
* When linking an executable with %t.so, the path %t.so will be recorded
in the DT_NEEDED entry if %t.so doesn't have DT_SONAME. .dynstr will
have varying lengths on different systems. Add -soname to make tests
more robust.

This improves readability and the behavior is consistent with GNU objdump.
The new test test/tools/llvm-objdump/X86/disassemble-section-name.s
checks we print newlines before and after "Disassembly of section ...:"

Current value using as a trap instruction (0xefefefef) is not a good choice
for MIPS because it's a valid MIPS instruction `swc3 $15,-4113(ra)`. This
patch replaces 0xefefefef by 0x04170001. For all MIPS ISA revisions before
R6, this value is just invalid instruction. Starting from MIPS R6 it's
a valid instruction `sigrie 1` which signals a Reserved Instruction exception.
mips-traps.s test case is added to test trap encoding. Other test cases
are modified to remove redundant checking.

This patch fills holes in executable sections with 0xd4 (ARM) or
0xef (MIPS). These trap instructions were suggested by Theo de Raadt.

Thunks are now generated per InputSectionDescription instead of per
OutputSection. This allows created ThunkSections to be inserted directly
into InputSectionDescription.
Changes in this patch:
- Loop over InputSectionDescriptions to find relocations to Thunks
- Generate a ThunkSection per InputSectionDescription
- Remove synchronize() as we no longer need it
- Move fabricateDefaultCommands() before createThunks
