[Patch] [PR27237] Fix documentation for -mthumb

["Ramana Radhakrishnan" <ramana dot radhakrishnan at arm dot com>]

Hi,

This is with respect to  http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27237

The ARM backend in the compiler will generate the directives for the
functions .arm or .thumb depending on the command line options and the
assembler will automatically switch ISA modes depending on these directives.
Hence it is not necessary to pass the -mthumb command line option.  However
if someone was assembling only a .S file using the driver and passed -mthumb
to the driver, he'd expect that the -mthumb option gets passed on to the
assembler. This patch attempts to make this explicit in the documentation.

        * doc/invoke.texi (ARM Options): Update documentation for -mthumb.

Ok to commit and backport to release branches ?

Cheers
Ramana
