Temporary workaround for a bad bug introduced by r121082 which replaced
t2LDRpci with t2LDRi12.
There are a couple of problems with this.
1. The encoding for the literal and immediate constant are different.
Note bit 7 of the literal case is 'U' so it can be negative.
2. t2LDRi12 is now narrowed to tLDRpci before constant island pass is run.
So we end up never using the Thumb2 instruction, which ends up creating a
lot more constant islands.

Implement support for custom target specific asm parsing of operands.
Motivation: Improve the parsing of not usual (different from registers or
immediates) operand forms.
This commit implements only the generic support. The ARM specific modifications
will come next.
A table like the one below is autogenerated for every instruction
containing a 'ParserMethod' in its AsmOperandClass
static const OperandMatchEntry OperandMatchTable[20] = {
/* Mnemonic, Operand List Mask, Operand Class, Features */
{ "cdp", 29 /* 0, 2, 3, 4 */, MCK_Coproc, Feature_IsThumb|Feature_HasV6 },
{ "cdp", 58 /* 1, 3, 4, 5 */, MCK_Coproc, Feature_IsARM },
A matcher function very similar (but lot more naive) to
MatchInstructionImpl scans the table. After the mnemonic match, the
features are checked and if the "to be parsed" operand index is
present in the mask, there's a real match. Then, a switch like the one
below dispatch the parsing to the custom method provided in
'ParseMethod':
case MCK_Coproc:
return TryParseCoprocessorOperandName(Operands);

Rewrite how the indirect call bonus is handled. This now works by:
a) Making it a per call site bonus for functions that we can move from
indirect to direct calls.
b) Reduces the bonus from 500 to 100 per call site.
c) Subtracts the size of the possible newly inlineable call from the
bonus to only add a bonus if we can inline a small function to devirtualize
it.
Also changes the bonus from a positive that's subtracted to a negative
that's added.
