Subject: [PATCH 048/123] LoongArch: Fix some test failures about TLS desc and
 TLS relaxation

There are two issues causing 11 test failures:

1. The TLS desc tests are matching the entire disassemble of a linked
   executable.  But if ld is configured --enable-default-hash-style=gnu
   (note that most modern distros use this option), the layout of the
   linked executables will be different and the immediate operands in
   the linked executables will also be different.  So we add
   "--hash-style=both" for these tests to cancel the effect of
   --enable-default-hash-style=gnu, like [x86_64 mark-plt tests].
2. By default objdump disassemble uses [pseudo-instructions] so "addi.w"
   is outputed as "li.w", causing mismatches in TLS relaxation tests.
   We can turn off the pseudo-instruction usage in objdump using "-M
   no-aliases" to fix them.

[x86_64 mark-plt tests]: 16666ccc91295d1568c5c2cb0e7600694840dfd9
[pseudo-instructions]: 17f9439038257b1de0c130a416a9a7645c653cb0
