Assorted warning fixes

gcc-9 flagged warnings at the places I'm patching here, all real bugs.

	* config/tc-alpha.c (md_apply_fix): Correct range checks for
	BFD_RELOC_ALPHA_NOP, BFD_RELOC_ALPHA_LDA, BFD_RELOC_ALPHA_BSR.
	* config/tc-arm.c (md_apply_fix): Use llabs rather than abs.
	* config/tc-csky.c (get_macro_reg_vals): Pass s to csky_show_error.

(cherry picked from commit 3ca4a8eca78b4d5e3fa308dbd21c67ebef09a261)
