f2e19d5dcf This increases the maximum for MVT::LAST_VALUETYPE 
This change doubles the allowable value for MVT::LAST_VALUETYPE. It does
this by doing several things.

1. Introduces MVT::MAX_ALLOWED_LAST_VALUETYPE which in this change has a
value of 64.  This value contains the current maximum for the
MVT::LAST_VALUETYPE.

2. Instead of checking "MVT::LAST_VALUETYPE <= 32", all of those uses
now become "MVT::LAST_VALUETYPE <= MVT::MAX_ALLOWED_LAST_VALUETYPE"

3. Changes the dimension of the ValueTypeActions from 2 elements to four
elements and adds comments ahead of the declaration indicating the it is
"(MVT::MAX_ALLOWED_LAST_VALUETYPE/32) * 2".  This at least lets us find
what is affected if and when MVT::MAX_ALLOWED_LAST_VALUETYPE gets
changed.

4. Adds initializers for the new elements of ValueTypeActions.

This does NOT add any types in MVT. That would be done separately.

This doubles the size of ValueTypeActions from 64 bits to 128 bits and
gives us the freedom to add more types for AVX.

40a5a1b39e Extend ScalarEvolution's multiple-exit support to compute exact 
trip counts in more cases.

Generalize ScalarEvolution's isLoopGuardedByCond code to recognize
And and Or conditions, splitting the code out into an
isNecessaryCond helper function so that it can evaluate Ands and Ors
recursively, and make SCEVExpander be much more aggressive about
hoisting instructions out of loops.

test/CodeGen/X86/pr3495.ll has an additional instruction now, but
it appears to be due to an arbitrary register allocation difference.

5c324d77d9 "The MMX_MASKMOVQ and MMX_MASKMOVQ64 instructions are labeled as MRMDestMem 
instructions, which implies that there is an explicit memory operand.  There is
(however) no explicit memory operand; although this is a store, the only memory
operand is implicit, indicated by DS:EDI.  This causes the table-generation code
for the disassembler to report an error."

soon.

5c0b16d0c4 change TLS_ADDR lowering to lower to a real mem operand, instead of matching as 
a global with that gets printed with the :mem modifier.  All operands to lea's 
should be handled with the lea32mem operand kind, and this allows the TLS stuff
to do this.  There are several better ways to do this, but I went for the minimal
change since I can't really test this (beyond make check).

This also makes the use of EBX explicit in the operand list in the 32-bit, 
instead of implicit in the instruction.

and generate calls to operand translation routines where needed.

something sensible.

763bad1a2b Generalize isLoopGuardedByCond's checking to consider two 
SCEVUnknowns with identical Instructions to be equal. This allows
it to analze cases such as the attached testcase, where the front-end
has cloned the loop controlling expression. Along with r73805, this
lets IndVarSimplify eliminate all the sign-extend casts in the
loop in the attached testcase.

04fb7c36a9 Revert r73790, and replace it with a significantly less ugly solution. Rather than trying to make the global reader-writer lock work, 
create separate recursive mutexes for each value map.  The recursive-ness fixes the double-acquiring issue, which having one per ValueMap
lets us continue to maintain some concurrency.
