5ae3571f75 This file was schizophrenic when it came to representing sizes. In some 
cases it represented them as 'unsigned's, which are not enough for 64-bit
hosts.  In other cases, it represented them as uint64_t's, which are
inefficient for 32-bit hosts.

This patch unifies all of the sizes to use size_t instead.

15774df4d3 Before doing expensive global analysis, check to make sure the pointer is 
not invalidated on entry and on exit of the block.  This fixes some N^2
behavior in common cases, and speeds up gcc another 5% to 22.35s.

e212d62a34 Minor simplification/speedup. Replaces a set lookup with a pointer comparison. 
This speeds up 176.gcc from 25.73s to 23.48s, which is 9.5%

e233b8c64b Eliminate generality that is not buying us anything. In particular, this 
will cause us to miss cases where the input pointer to a load could be value
numbered to another load.  Something like this:


  %X = load int* %P1
  %Y = load int* %P2

Those are obviously the same if P1/P2 are the same.  The code this patch
removes attempts to handle that.  However, since GCSE iterates, this doesn't
actually buy us anything: GCSE will first replace P1 or P2 with the other
one, then the load can be value numbered as equal.

Removing this code speeds up gcse a lot.  On 176.gcc in debug mode, this
speeds up gcse from 29.08s -> 25.73s, a 13% savings.

b48da39536 Remove the 3 HACK HACK HACKs I put in before, fixing them properly with 
the new TLI that is available.

Implement support for handling out of range shifts.  This allows us to
compile this code (a 64-bit rotate):

unsigned long long f3(unsigned long long x) {
  return (x << 32) | (x >> (64-32));
}

into this:

f3:
        mov %EDX, DWORD PTR [%ESP + 4]
        mov %EAX, DWORD PTR [%ESP + 8]
        ret

GCC produces this:

$ gcc t.c -masm=intel -O3 -S -o - -fomit-frame-pointer
..
f3:
        push    %ebx
        mov     %ebx, DWORD PTR [%esp+12]
        mov     %ecx, DWORD PTR [%esp+8]
        mov     %eax, %ebx
        mov     %edx, %ecx
        pop     %ebx
        ret

The Simple ISEL produces (eww gross):

f3:
        sub %ESP, 4
        mov DWORD PTR [%ESP], %ESI
        mov %EDX, DWORD PTR [%ESP + 8]
        mov %ECX, DWORD PTR [%ESP + 12]
        mov %EAX, 0
        mov %ESI, 0
        or %EAX, %ECX
        or %EDX, %ESI
        mov %ESI, DWORD PTR [%ESP]
        add %ESP, 4
        ret
