Add short_call function attribute for MIPS
gcc/
* config/mips/mips.c (mips_attribute_table): Add 'short_call'
attribute.
(mips_near_type_p): Add 'short_call' attribute as a synonym
for 'near'.
* doc/extend.texi (short_call): Document new function attribute.
gcc/testsuite
* gcc.target/mips/near-far-1.c: Add check for 'short_call'
attribute.
* gcc.target/mips/near-far-2.c: Likewise.
* gcc.target/mips/near-far-3.c: Likewise.
* gcc.target/mips/near-far-4.c: Likewise.
