d3c9d9447e Use uint16_t to store InstrNameIndices in MCInstrInfo. Add asserts to protect all 16-bit string table offsets. Also make sure the string to offset table string is not larger than 65536 characters since larger string literals aren't portable.

bb9dbb7d6b Missing change in r152106 for TinyPtrVector.

eea81f32cd Switch this code to use hash_combine_range rather than incremental calls 
to hash_combine. One of the interfaces could already do this, and the
other can just use a small buffer. This is a much more efficient way to
use the hash_combine interface, although I don't have any particular
benchmark where this code was hot, so I can't measure much of an impact.
It at least doesn't slow anything down.

f8cde7388e Cache the sized-ness of struct types, once we reach the steady state of 
"is sized". This prevents every query to isSized() from recursing over
every sub-type of a struct type. This could get *very* slow for
extremely deep nesting of structs, as in 177.mesa.

This change is a 45% speedup for 'opt -O2' of 177.mesa.linked.bc, and
likely a significant speedup for other cases as well. It even impacts
-O0 cases because so many part of the code try to check whether a type
is sized.

Thanks for the review from Nick Lewycky and Benjamin Kramer on IRC.

891495e676 No functionality change. Type::isSized() can be expensive, so avoid calling it 
until after other inexpensive tests.

3247af2949 Add <imp-def> operands when reloading into physregs. 
When an instruction only writes sub-registers, it is still necessary to
add an <imp-def> operand for the super-register.  When reloading into a
virtual register, rewriting will add the operand, but when loading
directly into a virtual register, the <imp-def> operand is still
necessary.
