7b80f3c39c now that the opcode is trivially exposed, start matching instructions 
by doing a binary search over the mnemonic instead of doing a linear
search through all possible instructions.  This implements rdar://7785064

e443a993fb emit the match table at global scope instead of within the 
MatchInstructionImpl. This makes it easier to read/understand
MatchInstructionImpl.

d323dac9bd special case the mnemonic operand of the instruction in the 
generated matcher, emiting it as a column in the MatchEntry
table instead of forcing it to go through classification and
everything else.  Making it be classified caused tblgen to
produce a ton of one-off classes for each mneumonic.  This
should reduce the size of the generated matcher significantly
while paving the way for future improvements.

72d2fb8001 The "ambiguous instructions" check only produces anything with -debug, 
so only do the N^2 loop with debug mode.

68f7c5b750 have tblgen detect when an instruction would have matched, but 
failed because a subtarget feature was not enabled.  Use this to
remove a bunch of hacks from the X86AsmParser for rejecting things
like popfl in 64-bit mode.  Previously these hacks weren't needed,
but were important to get a message better than "invalid instruction"
when used in the wrong mode.

This also fixes bugs where pushal would not be rejected correctly in
32-bit mode (just pusha).

45a204be76 have AsmMatcherEmitter.cpp produce the hunk of code that gets included 
into the middle of the class, and rework how the different sections of
the generated file are conditionally included for simplicity.

9feb462669 slightly improve the runtime and code size of the Intrinsics info table by not 
comparing the "llvm." prefix in the memcmp, and not storing it in the string literal.

f9e09104f1 Make tool_output_file's raw_ostream instance a member variable instead 
of a base class.

This makes it possible to unregister the file from FilesToRemove when
the file is done. Also, this eliminates the need for
formatted_tool_output_file.
