While handling the comments of Tom related to
  [RFC] Have an option to tell GDB to detect and possibly handle mismatched exec-files.
  https://sourceware.org/ml/gdb-patches/2019-12/msg00621.html
I saw that GDB warnings are produced ignoring the given styles.

This patch:
  * ensures that style markups are properly handled by "warning".
  * changes 'set/show data-directory' so that file style is used
    in warnings and in 'show message'
  * changes all other messages in top.c to use file style when appropriate.
  * Uses the above data-directory changes in gdb.base/style.exp

Just like their LD1RQ{H,W,D} counterparts, as per the specification the
index registers get scaled by element size.

According to the specification these permit the Q bit to control the
vector length operated on, and hence this bit should not already be set
in the opcode table entries (it rather needs setting dynamically). Note
how the test case output did also not match its input. Besides
correcting the test case also extend it to cover both forms.

According to the specification, and in line with the pre-existing
predicate forms, the mnemonics do not include an 'i'.

There's just one bit of difference to the 32-bit element form, as
per the documentation.

Oldish gcc warns about local variables shadowing outer scope ones.
Additionally %lx is not (always) suitable to print the result of
bfd_get_32().

This fixes PR 25210 by specifying the the correct ELF class for AArch64 stubs.
After doing this the stub section starts behaving like a normal object file
loaded from disk.  That is SEC_LINKER_CREATED causes us to have to write the
section manually.

This flag was added as a fix for PR 24753.  I believe that
fix to still be correct as linker created sections don't have a size on disk
and it fixes the Arm bootstrap regression. But in this case specifying the
correct section class also makes the stub section not be considered by
compress.c.

So I'm partially revert this change so that we don't have to manage the section
manually as implied by SEC_LINKER_CREATED.

The variable INSTALL_PROGRAM_ENV sets up STRIPPROG for the cross-compiler.

If this is not done, the host 'strip' is used, and fails:
