fe0e921f00 PR26513, 629310abec breaks assembling PowerPC Linux kernels
Inserting with replacement is wrong for some gas hash table uses.
This patch implements an htab_insert that conditionally replaces, and
similarly for str_hash_insert.  str_hash_insert with replace=0 is
roughly equivalent to the older hash_insert, and str_hash_insert with
replace=1 to the older hash_jam, but return values are different.  I
found it useful to know whether the slot was occupied prior to
inserting/replacing.  I've also reinstated the fatal errors on messing
up opcode tables with duplicates.

	PR 26513
	* hash.h (htab_insert): Update prototype and comment.
