e06344da06 Some of the tests build an executable with llvm-gcc. For this to work, llvm-gcc 
needs to find some libraries, which may require searching the directories given
by LIBRARY_PATH on curiously configured systems.  So pass on LIBRARY_PATH.

57c4ffb2f3 Use float64 instead of int64 vector elements for NEON vget_low and vget_high 
functions, since int64 is not a legal type and using it leads to inefficient
code.  PR8036.

b79a03a3ca For each instruction itinerary class, specify the number of micro-ops each 
instruction in the class would be decoded to. Or zero if the number of
uOPs must be determined dynamically.

This will be used to determine the cost-effectiveness of predicating a
micro-coded instruction.

a83eb43cb8 A script that tests a certain release candidate in several modes. It does a 
2-phase build of llvm and llvm-gcc, similar to what the buildbots do, and runs
the regression testsuite.

Things to do:

- Work out some bugs with llvm-gcc flags.
- Not all platforms support ObjC.
- Run the test-suite.

9f2c0da214 generalize my previous operand loc info hack. If the same operand 
is busted for all variants, report it as the location.  This allows
us to get the operand right for bugs like:

t.s:3:12: error: invalid operand for instruction
	outb %al, %gs
	          ^

Even though there are reg/imm and reg/reg forms of this instruction.

6bfa0d9988 in the case where an instruction only has one implementation 
of a mneumonic, report operand errors with better location
info.  For example, we now report:

t.s:6:14: error: invalid operand for instruction
        cwtl $1
             ^

but we fail for common cases like:

t.s:11:4: error: invalid operand for instruction
   addl $1, $1
   ^

because we don't know if this is supposed to be the reg/imm or imm/reg
form.

bb5e19cb63 Now that we know if we had a total fail on the instruction mnemonic, 
give a more detailed error.  Before:

t.s:11:4: error: unrecognized instruction
   addl $1, $1
   ^
t.s:12:4: error: unrecognized instruction
   f2efqefa $1
   ^

After:

t.s:11:4: error: invalid operand for instruction
   addl $1, $1
   ^
t.s:12:4: error: invalid instruction mnemonic 'f2efqefa'
   f2efqefa $1
   ^

This fixes rdar://8017912 - llvm-mc says "unrecognized instruction" when it means "invalid operands"

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

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,

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).
