[Patch ARM] PR48203 Don't split call from it's CALL_ARG_LOCATION note.

[Ramana Radhakrishnan]

Hi,

The attached patch fixes PR48203 for ARM by not splitting the call from 
it's call_arg_location note while emitting literal pools. This is 
similar to the patch for s390 and I notice one for sh that fixes a 
similar issue.

The other patch in the audit trail by Jakub is needed to fix up the 
issue with ICE in mem_loc_descriptor which also shows up in the 
testsuite runs if the attached patch is tested alone.

Committed after testruns on qemu using cross-builds on armv7-a and 
verifying that bootstrap is restored.

cheers
Ramana
