Jakob Stoklund Olesen 4029596f93 Use the fast register allocator by default for -O0 builds. 
This affects both llvm-gcc and clang.

Jakob Stoklund Olesen 818e4df2b4 Use readsWritesVirtualRegister instead of counting uses and defs when inserting 
spills and reloads.

This means that a partial define of a register causes a reload so the other
parts of the register are preserved.

The reload can be prevented by adding an <imp-def> operand for the full
register. This is already done by the coalescer and live interval analysis where
relevant.

Jakob Stoklund Olesen 42c642cd24 Add full register <imp-def> operands when the coalescer is creating partial 
register updates.

These operands tell the spiller that the other parts of the partially defined
register are don't-care, and a reload is not necessary.

Devang Patel df84e8baf7 Speedup bitcode writer. Do not walk all values for all functions to emit function local metadata. In one testcase, probably worst case scenario, the 70x speed up is seen.

Jakob Stoklund Olesen a8ad97743d Slightly change the meaning of the reMaterialize target hook when the original 
instruction defines subregisters.

Any existing subreg indices on the original instruction are preserved or
composed with the new subreg index.

Also substitute multiple operands mentioning the original register by using the
new MachineInstr::substituteRegister() function. This is necessary because there
will soon be <imp-def> operands added to non read-modify-write partial
definitions. This instruction:

  %reg1234:foo = FLAP %reg1234<imp-def>

will reMaterialize(%reg3333, bar) like this:

  %reg3333:bar-foo = FLAP %reg333:bar<imp-def>

Finally, replace the TargetRegisterInfo pointer argument with a reference to
indicate that it cannot be NULL.
