Enable thumb1_gen_const_int to generate RTL or asm depending on the
context, so that we avoid duplicating code to handle constants in
Thumb-1 with -mpure-code.
Use a template so that the algorithm is effectively shared, and
rely on two classes to handle the actual emission as RTL or asm.
The generated sequence is improved to handle right-shiftable and small
values with less instructions. We now generate:
128:
movs r0, r0, #128
264:
movs r3, gcc-mirror#33
lsls r3, gcc-mirror#3
510:
movs r3, #255
lsls r3, #1
512:
movs r3, #1
lsls r3, gcc-mirror#9
764:
movs r3, #191
lsls r3, gcc-mirror#2
65536:
movs r3, #1
lsls r3, gcc-mirror#16
0x123456:

lsls r3, gcc-mirror#8

0x1123456:
movs r3, #137 ;0x89
lsls r3, gcc-mirror#8
adds r3, gcc-mirror#26 ;0x1a
lsls r3, gcc-mirror#8
adds r3, gcc-mirror#43 ;0x2b
lsls r3, #1
0x1000010:
movs r3, gcc-mirror#16
lsls r3, gcc-mirror#16
adds r3, #1
lsls r3, gcc-mirror#4
0x1000011:
movs r3, #1
lsls r3, gcc-mirror#24
adds r3, gcc-mirror#17
-8192:
movs r3, #1
lsls r3, gcc-mirror#13
rsbs r3, #0
The patch adds a testcase which does not fully exercise
thumb1_gen_const_int, as other existing patterns already catch small
constants. These parts of thumb1_gen_const_int are used by
arm_thumb1_mi_thunk.

This is the first pass at implementing macros more testcases are needed. This does not support repetition matchers but it supports simple declarative macros and transcribes them. The approach taken here is that we reuse our existing parser to call the apropriate functions as specified as part of the MacroFragmentType enum if the parser does not have errors parsing that item then it must be a match. Then once we match a rule we have a map of the token begin/end offsets for each fragment match, this is then used to adjust and create a new token stream for the macro rule definition so that when we feed it to the parser the tokens are already substituted. The resulting expression or item is then attached to the respective macro invocation and this is then name resolved and used for hir lowering. Fixes gcc-mirror#17 gcc-mirror#22 Addresses #573
