* invoke.texi: Add -mlong32 documentation.
* config/mips/mips.h (mips_explicit_type_size_string): New.
(TARGET_SWITCHES): Add 'long32'.
(TARGET_OPTIONS): Add 'explicit-type-size'.
(CC1_SPECS): Set -mexplicit-type-size.
(LONG_MAX_SPEC): Change a use of 'no-long64' to 'long32'.

Pointer size now depends on both size longs and size of GP
registers.

If none of @samp{-mlong32}, @samp{-mlong64}, or @samp{-mint64} are set,

the size of ints, longs, and pointers depends on the ABI and ISA choosen.

For @samp{-mabi=32}, and @samp{-mabi=n32}, ints and longs are 32 bits

wide. For @samp{-mabi=64}, ints are 32 bits, and longs are 64 bits wide.

For @samp{-mabi=eabi} and either @samp{-mips1} or @samp{-mips2}, ints

are 32 bits, and longs are 64 bits wide. The width of pointer types is

the smaller of the width of longs or the width of general purpose
