a241dec2fc Rename GR8_ABCD to GR8_ABCD_L and create GR8_ABCD_H, and use these 
to precisely describe the h-register subreg register classes.
Thanks to Jakob Stoklund Olesen for spotting this and for the
initial patch!

Also, make getStoreRegOpcode and getLoadRegOpcode aware of the
needs of h registers.

5c4f46c2e9 Under unusual circumstances (jitting a function that causes the creation of 
another stub, but then never calling the jitted function) can cause the JIT to
leave a stub in place. Judging by the comments this is a known deficiency, so
we're just not going to use AssertingVH for the StubToFunctionTy map.

Also shorten some lines longer than 80 columns.

This fixes the "make check" failure with ocaml on x86-64 linux.

f84ee5d944 Add two new record types to the blockinfo block: 
BLOCKNAME and SETRECORDNAME.  This allows a bitcode
file to be self describing with pretty names for 
records and blocks in addition to numbers.  This
enhances llvm-bcanalyzer to use this to print prettily.

a43dcba929 Make a major API change to BitstreamReader: split all the reading 
state out of the BitstreamReader class into a BitstreamCursor class.
Doing this allows the client to have multiple cursors into the same
file, each with potentially different live block stacks and
abbreviation records.

034358326a Allow aliasee to be a GEP or bitcast instead of just a bitcast. 
The real fix for this whole mess is to require the operand of the
alias to be a *GlobalValue* (not a general constant, including 
constant exprs) but allow the operand and the alias type to be
unrelated.

This fixes PR4066

285a5fb1d5 Fix g++-4.4.0 warning, it was causing llvm-nm to fail on wrapped BC files: 
Path.cpp:59: warning: case label value exceeds maximum value for type
magic[0] is a (signed) char, but some case values are unsigned (e.g. 0xde).
When magic[0] was 0xde, the switch has taken the default branch instead of case
0xde branch.
Apparently this was the behaviour with older versions of gcc too, but not with g++.
Now g++-4.4 behaves as gcc, and ignores unsigned case values out of range signed
range.

696a04eba2 Do not share a single unknown val# for all the live ranges merged into a physical sub-register live interval. When coalescer is merging in clobbered virtaul register live interval into a physical register live interval, give each virtual register val# a separate val# in the physical register live interval. Otherwise, the coalescer would have lost track of the definitions information it needs to make correct coalescing decisions.

493c3bcdc0 Fix PR 4057, a crash doing float->char const folding. 
This particular one is undefined behavior (although this
isn't related to the crash), so it will no longer do it
at compile time, which seems better.

0ac8a0cf95 Adjust a comment to reflect what the code does. Splitting a 64-bit argument 
between registers and the stack may be required with the APCS ABI, but it
isn't tied to using a particular version of the ARM architecture.

2a47f01759 Fix up some problems with getCopyToReg and getCopyFromReg nodes being 
chained and "flagged" together.  I also made a few changes to handle the
chain and flag values more consistently.  I found these problems by
inspection so I'm not aware of anything that breaks because of them
(thus no testcase).
