[PATCH, PR target/65495] List available languages for all chkp options

[Ilya Enkovich <enkovich dot gnu at gmail dot com>]

Hi,

This patch avoids various ICEs due to -fcheck-pointer-bounds used for not supported languages.  All options get the same languages list.  Bootstrapped and tested on x86_64-unknown-linux-gnu.  Does it look OK?

Thanks,
Ilya

 Use zero bounds for all incoming arguments in 'main' function.  It helps when
 instrumented binaries are used with legacy libs.

 Forces Pointer Bounds Checker to use narrowed bounds for address of the first
 field in the structure.  By default pointer to the first field has the same
 bounds as pointer to the whole structure.

 Control how Pointer Bounds Checker handle pointers to object fields.  When
 narrowing is on, field bounds are used.  Otherwise full object bounds are used.
