e6f350d755 Turn a 2-address instruction into a 3-address one when it's profitable even if the two-address operand is killed. 
e.g.
%reg1024<def> = MOV r1
%reg1025<def> = ADD %reg1024, %reg1026
r0            = MOV %reg1025

If it's not possible / profitable to commute ADD, then turning ADD into a LEA saves a copy.

0b0cd9113a Optimize some 64-bit multiplication by constants into two lea's or one lea + shl since imulq is slow (latency 5). e.g. 
x * 40
=>
shlq    $3, %rdi
leaq    (%rdi,%rdi,4), %rax

This has the added benefit of allowing more multiply to be folded into addressing mode. e.g.
a * 24 + b
=>
leaq    (%rdi,%rdi,2), %rax
leaq    (%rsi,%rax,8), %rax

5d088fee7c Fix a bug in spill weight computation. If the alias is a super-register, and the super-register is in the register class we are trying to allocate. Then add the weight to all sub-registers of the super-register even if they are not aliases. 
e.g. allocating for GR32, bh is not used, updating bl spill weight.                                                                                                        
     bl should get the same spill weight otherwise it will be choosen                                                                                              
     as a spill candidate since spilling bh doesn't make ebx available.
This fix PR2866.

7d6d4b360f Do not fold away subreg_to_reg if the source register has a sub-register index. That means the source register is taking a sub-register of a larger register. e.g. On x86 
%RAX<def> = ...
%RAX<def> = SUBREG_TO_REG 0, %EAX:3<kill>, 3
The first def is defining RAX, not EAX so the top bits were not zero-extended.

ff81ebf758 Disable the "call to immediate" optimization on x86-64. It is 
not safe in general because the immediate could be an arbitrary
value that does not fit in a 32-bit pcrel displacement.  
Conservatively fall back to loading the value into a register
and calling through it.

We still do the optzn on X86-32.

0b18e59336 Fix codegen to compute the size of an allocation by multiplying the 
size by the array amount as an i32 value instead of promoting from
i32 to i64 then doing the multiply.  Not doing this broke wrap-around
assumptions that the optimizers (validly) made.  The ultimate real
fix for this is to introduce i64 version of alloca and remove mallocinst.
