Subject: final.c, output.h (fprint_whex, [...]): New functions serving as fast
 replacements for fprintf() integer to string...

	* final.c, output.h (fprint_whex, fprint_w, fprint_ul, sprint_ul):
	New functions serving as fast replacements for fprintf() integer
	to string conversions. They were used in the following changes.
	* final.c (sprint_ul_rev): Internal helper for the above.
	(output_addr_const): case CONST_INT: don't use fprintf().
	* elfos.h (ASM_GENERATE_INTERNAL_LABEL): Don't use sprintf("%u"),
	use sprint_ul() and stpcpy() which are much faster.
	(TARGET_ASM_INTERNAL_LABEL): Define as default_elf_internal_label.
	(ELF_ASCII_ESCAPES, ELF_STRING_LIMIT): Are the old ESCAPES and
	STRING_LIMIT macros.
	(ASM_OUTPUT_LIMITED_STRING, ASM_OUTPUT_ASCII): Macros now just
	call respective functions that provide the same
	functionality. Those are default_elf_asm_output_limited_string()
	and default_elf_asm_output_ascii() in varasm.c.
	* varasm.c: Fixed some whitespace inconsistencies.
	(default_elf_asm_output_limited_string)
	(default_elf_asm_output_ascii): The above macros from elfos.h are
	implemented here as these functions, avoiding superfluous calls to
	fprintf().
	(default_elf_internal_label): Hook for
	targetm.asm_out.internal_label and ASM_OUTPUT_DEBUG_LABEL.
	* i386.c: Don't call fprintf("%u") but fprint_ul() instead.
	* defaults.h (ASM_OUTPUT_LABEL, ASM_OUTPUT_INTERNAL_LABEL):
	Expanded the macros on multiple lines for readability.
	(ASM_OUTPUT_LABELREF): Have two calls to fputs() instead of one to
	asm_fprintf().
	* dwarf2asm.c (dw2_assemble_integer, dw2_asm_output_data)
	(dw2_asm_data_uleb128, dw2_asm_delta_uleb128)
	(dw2_asm_delta_sleb128): Convert fprintf() calls to the new
	faster functions.
	* dwarf2out.c (dwarf2out_source_line): Convert fprintf() calls to
	the new faster functions.
