tcg: Add field extraction primitives 

Adds tcg_gen_extract_* and tcg_gen_sextract_* for extraction of
fixed position bitfields, much like we already have for deposit.

@ -314,11 +314,27 @@ The bitfield is described by POS/LEN, which are immediate values:
LEN - the length of the bitfield
POS - the position of the first bit, counting from the LSB
For example, pos=8, len=4 indicates a 4-bit field at bit 8.
This operation would be equivalent to
For example, "deposit_i32 dest, t1, t2, 8, 4" indicates a 4-bit field
at bit 8. This operation would be equivalent to
dest = (t1 & ~0x0f00) | ((t2 << 8) & 0x0f00)
* extract_i32/i64 dest, t1, pos, len
* sextract_i32/i64 dest, t1, pos, len
Extract a bitfield from T1, placing the result in DEST.
The bitfield is described by POS/LEN, which are immediate values,
as above for deposit. For extract_*, the result will be extended
to the left with zeros; for sextract_*, the result will be extended
to the left with copies of the bitfield sign bit at pos + len - 1.
For example, "sextract_i32 dest, t1, 8, 4" indicates a 4-bit field
at bit 8. This operation would be equivalent to
dest = (t1 << 20) >> 28
(using an arithmetic right shift).
* extrl_i64_i32 t0, t1
For 64-bit hosts only, extract the low 32-bits of input T1 and place it
