* dbxread.c (MSYMBOL_SIZE): New macro.

Browse Source 
(end_psymtab): Use MSYMBOL_SIZE to extract size from minimal symbol.
	* elfread.c (elf_symtab_read): If ELF symbol is "special",
	such as a MIPS16 function, mark minimal symbol as special too.
	* mips-tdep.c (pc_is_mips16): New function to check whether
	a function is MIPS16 by looking at the minimal symbol.  Use
	pc_is_mips16 throughout instead of IS_MIPS16_ADDR macro.
	* config/mips/tm-mips.h (SYMBOL_IS_SPECIAL, MAKE_MSYMBOL_SPECIAL,
	MSYMBOL_IS_SPECIAL, MSYMBOL_SIZE): New functions for setting/testing
	"special" MIPS16 bit in ELF and minimal symbols.
	* mdebugread.c (parse_partial_symbols): Don't construct a partial
	symbol table for a file that already has one.

	* configure.tgt: Support TX19.
	* config/mips/tm-tx19.h, config/mips/tm-tx19l.h, config/mips/tx19.mt,
	config/mips/tx19l.mt: New files for TX19.

/* Macros for setting and testing a bit in a minimal symbol that
marks it as 16-bit function. The MSB of the minimal symbol's
"info" field is used for this purpose. This field is already
being used to store the symbol size, so the assumption is
that the symbol size cannot exceed 2^31.
SYMBOL_IS_SPECIAL tests whether an ELF symbol is "special", i.e. refers
to a 16-bit function
MAKE_MSYMBOL_SPECIAL sets a "special" bit in a minimal symbol to mark it
as a 16-bit function
MSYMBOL_IS_SPECIAL tests the "special" bit in a minimal symbol
MSYMBOL_SIZE returns the size of the minimal symbol, i.e.
the "info" field with the "special" bit masked out
