[mips] Use uimm5 and uimm6 instead of shamt and imm, if the immediate has to fit
into a 5-bit or 6-bit field.

Verifier is updated accordingly.

[mips] Add definition of instruction "drotr32" (double rotate right plus 32).

Remove verifier check that attribute 'builtin' is only applied to calls to
functions marked 'nobuiltin'. That approach doesn't play well with LTO, and
there's no harm in marking a call as 'builtin' if it was going to be a builtin
regardless.

[mips] Place parentheses around && to silence warning.

[mips] Enhance command line option "-mno-ldc1-sdc1" to expand base+index double
precision loads and stores as well as reg+imm double precision loads and stores.

Previously, expansion of loads and stores was done after register allocation,
but now it takes place during legalization. As a result, users will see double
precision stores and loads being emitted to spill and restore 64-bit FP registers.
