7065309739 Formatting: kill off "stealth whitespace" 
"Stealth whitespace" makes it harder to read diffs, and just generally
cause unwanted weirdness.  Do a source-wide pass to get rid of it.

37d88e4125 Don't confuse suffixed hexadecimal with floating-point 
1e30 is a floating-point constant, but 1e30h is not.  The scanner
won't know that until it sees the "h", so make sure we keep enough
state to be able to distinguish "1e30" (a possible hex constant) from
"1.e30", "1e+30" or "1.0" (unabiguously floating-point.)

d0b0d28f42 Unbreak relative references to immediate addresses 
Remove bogus "treat labels different from immediates" code, which
would result in generating of a relative mod/rm but without adjusting
the address accordingly.

dc467ba8af Support __float*__ for floating-point numbers in expressions 
Add special operators to allow the use of floating-point constants in
contexts other than DW/DD/DQ/DT/DO.

As part of this checkin, make MAX_KEYWORD generated by tokhash.pl,
since it knows what all the keywords are so it can tell which one is
the longest.

fc565dd362 Implement INVLPGA according to the documentation 
INVLPGA is defined as taking rax,ecx but "the portion of rax used to
form the address is determined by the effective address size", so it
is really ax/eax/rax.

e31747e95b Unify all standard IEEE floating-point formats; add 128-bit 
Unify all the standard IEEE formats into one function, add support for
IEEE standard 128-bit floating point numbers.

The 80-bit format is still special since it explicitly represents the
integer portion.

cf5180a955 Actually generate SSE5 instructions 
This checkin completes what is required to actually generate SSE5
instructions.  No support in the disassembler yet.

This checkin covers:

- Support for actually generating DREX prefixes.
- Support for matching operand "operand X must match Y"

9ab60dabcc Simple performance benchmarks: label, macro and token lookups 
Simple scripts to generate performance benchmarks for label,
macro and token lookups.  The label and macro lookups are simple
numerical sequences; it may be desirable to add some more
sophisticated algorithms for producing tokens in case we want to
compare different hash functions against each other.
